An all-in-one computer eliminates the bulky tower hiding under your desk by integrating the motherboard, storage, and processor directly behind the display panel. This single-cable elegance frees up floor space and reduces clutter while still delivering the full desktop operating system most people need for office work, browsing, streaming, and light creative tasks. The challenge is finding a model that pairs genuine daily usability with reasonable component selection — many entry-level systems cut corners on RAM speed, SSD capacity, or CPU core count that become obvious within months of use.

I’m Mo Maruf — the founder and writer behind The Tools Trunk. Every recommendation here comes from cross-referencing CPU benchmarks, real memory bandwidth tests, panel specifications, and verified buyer feedback on reliability and peripheral quality across the affordable all-in-one segment.

After carefully reviewing the hardware specs, port selection, and long-term value of the current market lineup, you can confidently find the right machine by focusing on processor generation, RAM capacity, and storage configuration rather than brand names alone. This guide breaks down the best affordable all in one computer options across multiple budget tiers and use cases.

How To Choose The Best Affordable All In One Computer

The all-in-one market spans everything from bargain-bin processors with minimal RAM to near-workstation configurations. Understanding the specific component trade-offs helps you spend only on what genuinely improves your experience.

Processor Generations and Core Counts

Most affordable all-in-one computers ship with Intel N-series processors such as the N100 or N200 — quad-core chips originally designed for low-power laptops. These handle basic web browsing, document editing, and video playback without complaint, but they struggle with heavy multitasking, large spreadsheets, or photo editing. Stepping up to an Intel Core i3-N305 or a Core i5 processor dramatically improves snappiness during real-world use because of higher clock speeds and additional performance cores. Pay attention to whether the CPU is an N-series or U-series part; a U-series chip like the i5-13420H uses significantly more power but delivers roughly double the multi-threaded performance.

RAM and Storage Configurations

8GB of RAM has become the bare minimum in 2025. If you plan to keep the machine for more than two years, 16GB is the safer investment — modern web browsers, collaboration tools, and operating system overhead can consume 6-8GB before you open a single heavy application. On the storage side, an NVMe SSD is non-negotiable; the difference between a SATA-based SSD and an NVMe drive is immediately noticeable when booting and launching software. A 512GB NVMe SSD offers the best balance of speed and capacity for most home users, while 1TB gives breathing room for media libraries and installed software without worrying about external drives.

Display Technology and Panel Quality

Affordable models often pair VA panels with FHD resolution. VA panels offer decent contrast but narrower viewing angles than IPS panels, which can be noticeable when two people look at the screen from slightly different positions. IPS panels with 99% sRGB coverage deliver more accurate colors and better off-axis clarity, making them worthwhile for anyone who edits photos, watches video content, or simply wants a screen that looks consistent from any seated position. Anti-glare coatings and low blue light certifications such as TÜV Rheinland reduce eye fatigue during long work sessions, while refresh rates above 60Hz (common on newer models) provide smoother cursor movement and scrolling.

Connectivity and Expandability

Port selection determines how easily you can connect peripherals, external monitors, and storage devices without a separate hub. USB-C with 10Gbps data transfer, an HDMI port for a secondary display, and at least two USB-A ports for a keyboard and mouse are the baseline. Some all-in-ones include HDMI-in ports that let you use the display as a monitor for a gaming console or streaming stick — a useful dual-purpose feature absent from most desktop towers. Wi-Fi 6 and Bluetooth 5.2 provide faster wireless file transfers and more stable connections with modern routers, so prioritize these over older Wi-Fi 5 implementations.

In‑Depth Reviews

Best Overall

1. Lenovo ThinkCentre 27″ i5-13420H All-in-One

Intel Core i5-13420H100Hz IPS Panel

The Lenovo ThinkCentre 27-inch AIO sits at the intersection of genuine performance and reasonable cost. Its Core i5-13420H processor packs eight cores — four performance and four efficiency — that can turbo up to 4.6 GHz, enabling smooth multitasking across a dozen browser tabs, office applications, and light photo editing without the lag characteristic of N-series chips. The 100Hz refresh rate on the IPS panel is a noticeable upgrade over the standard 60Hz, making cursor movements feel fluid and reducing perceived stutter when scrolling long documents.

With 16GB of DDR5 RAM and a 512GB NVMe SSD, this machine skips the compromise many affordable all-in-ones make on memory bandwidth. DDR5 provides higher data transfer rates than DDR4, which directly benefits integrated graphics performance when handling 4K video playback or basic creative software. The low blue light certification and anti-glare coating mean less eye fatigue during full workdays, and the 99% sRGB color coverage ensures photos and videos display with accurate saturation.

The port selection reinforces its professional positioning: USB-C 3.2 Gen 2 for fast data transfers, both HDMI-out and HDMI-in so you can either extend to a second monitor or use the 27-inch display with a game console, plus an Ethernet port for reliable wired networking. A wired keyboard and mouse are included, though the keyboard has a basic membrane feel. Overall, this is the strongest balance of CPU, display quality, RAM, and I/O at this tier.

What works

  • True eight-core CPU performance
  • 100Hz IPS panel with 99% sRGB
  • DDR5 RAM and NVMe storage
  • HDMI-in port for console use

What doesn’t

  • Included keyboard feels basic

2. Lenovo IdeaCentre 27″ i7-13620H All-in-One

Intel Core i7-13620H10 Cores / 16 Threads

The IdeaCentre 27 brings a proper 10-core processor to the all-in-one form factor — six performance cores and four efficiency cores in the i7-13620H, with a maximum turbo frequency of 4.9 GHz. This is the kind of CPU that handles video editing timelines, large photo libraries, and data-heavy spreadsheets comfortably, tasks where N-series processors would stutter and stall. The 27-inch IPS display maintains 99% sRGB coverage with a three-side borderless design that makes the screen feel larger than its 1920×1080 resolution suggests.

Where this configuration makes trade-offs is memory. It ships with 8GB of DDR5-5200 RAM rather than 16GB, which means you may hit the ceiling sooner during heavy multitasking. The 512GB PCIe 4.0 NVMe SSD is fast and adequately sized, but users who keep large media libraries will need to budget for an external drive. The HARMAN-tuned speakers and 5MP webcam with dual microphones deliver above-average video call quality, and the 5MP camera captures clearer detail than the typical 720p sensors found on budget models.

Connectivity is well-rounded with USB-C 10Gbps, USB-A 10Gbps, HDMI-in and HDMI-out 2.1, plus Wi-Fi 6 and Bluetooth 5.2. The Luna Grey finish looks professional and resists fingerprints better than glossy white plastics. The IdeaCentre is one of the few affordable all-in-ones that can genuinely serve as a primary workstation for creative professionals on a budget, provided you’re comfortable adding more RAM later or working within 8GB for now.

What works

  • 10-core i7 processor is genuinely fast
  • 27-inch borderless IPS with 99% sRGB
  • 5MP webcam and HARMAN speakers
  • Dual HDMI ports (in and out)

What doesn’t

  • Only 8GB RAM in base config
  • No RAM upgrade slots accessible without disassembly
  • Some units reported as defective within days

Core 7 150U1TB NVMe SSD

Dell’s 27-inch all-in-one represents the premium end of the affordable spectrum, with the Core 7 150U processor bridging the gap between mid-range and high-end desktop performance. The 150U features 10 cores and a max turbo of up to 5 GHz, paired with 16GB of DDR5 RAM and a generous 1TB NVMe SSD — enough storage to keep your entire application suite, photo library, and several large projects installed simultaneously without reaching for an external drive. The FHD IPS display inherits Dell’s ComfortView Plus technology, which reduces blue light emissions without introducing the warm yellow tint common on software-based filters.

The 5MP infrared webcam supports Windows Hello facial recognition for password-free login, and the HDR technology helps maintain balanced exposure even when your home office has challenging window lighting. The pop-up camera mechanism provides physical privacy assurance — push it down to hide the lens completely. Dell also includes 1 Year Onsite Service, meaning a technician will come to your location if a hardware issue cannot be resolved remotely, which adds tangible peace of mind compared to mail-in-only warranty models.

Dual Bluetooth speakers with Dolby Atmos spatial sound produce fuller audio than the thin speakers found on budget AIOs, making casual video watching and music playback genuinely enjoyable without external speakers. The stand includes a clever keyboard-storage nook underneath the display, keeping the desk surface clean. The main drawbacks are the premium positioning relative to similarly equipped competitors and the fact that Microsoft Office comes only as a 30-day trial rather than a permanent license.

What works

  • 1TB NVMe SSD offers plenty of local space
  • ComfortView Plus blue light reduction
  • Onsite warranty service included
  • Pop-up webcam for physical privacy

What doesn’t

  • Higher price than comparable configs

4. Dell 24 Touch All-in-One Core 5 120U

Core 5 120UFHD Touch Display

This Dell 24-inch model is the only touchscreen option in this roundup, making it a standout for scenarios where direct display interaction speeds up workflow — medical professionals navigating patient records, educators demonstrating software, or creative users who prefer pinch-zoom over mouse scroll. The Core 5 120U processor delivers strong mid-range performance with a max turbo of 5 GHz and 12MB of cache, paired with 16GB of DDR5 RAM that keeps multiple applications responsive. The 23.8-inch FHD IPS panel supports touch input smoothly, and the 99% sRGB coverage ensures consistent colors even as you tilt the display between 0 and 20 degrees.

Dell’s ComfortView Plus technology is present here as well, reducing blue light without a color shift. The 5MP IR camera handles video calls with excellent clarity and supports Windows Hello login. The touch functionality extends naturally to Windows 11 gestures — swiping between virtual desktops, scrolling with a finger, and tapping to open files feels intuitive. The included wireless keyboard and mouse are full-size and comfortable for extended typing sessions, unlike the cramped peripherals bundled with some budget all-in-ones.

Dual speakers with Dolby Atmos produce room-filling audio that easily handles movies and music without external speakers. One minor ergonomic note: the camera is fixed in position and does not tilt independently, so if the monitor height doesn’t align with your face, you may need to adjust the entire display or use a separate webcam. The touchscreen also adds some glare compared to the matte finishes of non-touch models, so consider lighting placement if you work near a window.

What works

  • Responsive 10-point touch display
  • Core 5 120U with 16GB DDR5
  • 5MP IR camera with Windows Hello
  • Dolby Atmos dual speakers

What doesn’t

  • Camera angle is not adjustable

5. Dell 24 All-in-One Core 3 100U

Core 3 100UComfortView Plus IPS

The Dell 24 EC24250 with the Core 3 100U processor is a thoughtfully balanced mid-range all-in-one that avoids the common pitfall of pairing a decent CPU with insufficient RAM. The 100U is a 5-core, 6-thread processor (2 performance cores + 4 efficiency cores) that operates up to 4.7 GHz — notably faster than any N-series chip and capable of handling moderate multitasking like running office software alongside streaming music and a dozen browser tabs. The 8GB of DDR5 RAM is adequate for typical home office use, though power users may find themselves wishing for 16GB within the first year of ownership.

The 23.8-inch IPS panel with 99% sRGB coverage and 50% higher contrast than previous Dell AIO generations produces rich, accurate colors. The higher refresh rate — 66% faster than the prior generation — makes scrolling feel smoother and reduces perceived motion blur. ComfortView Plus remains active at all hardware levels, reducing blue light without a yellow tint, which is a meaningful difference from software-based night modes that wash out color accuracy. The 5MP IR camera supports Windows Hello and includes HDR to compensate for poor room lighting.

Dell includes 1 Year Onsite Service and 6 Months Dell Migrate for transferring files from an old PC. The wireless keyboard and mouse are full-size and solid performers. The main limitation is the 8GB RAM ceiling — the system uses integrated graphics that share system memory, so gaming or video editing will feel constrained. For email, browsing, document creation, spreadsheets, and video streaming, this Dell delivers a polished, reliable experience with the backing of Dell’s onsite service network.

What works

  • Core 3 100U is noticeably faster than N-series
  • IPS panel with 99% sRGB and high contrast
  • ComfortView Plus at hardware level
  • Onsite warranty included

What doesn’t

  • 8GB RAM is entry-level for this class

Octa-Core Value

6. Lenovo 24″ i3-N305 All-in-One

Intel Core i3-N3058 Cores / 3.8 GHz

Lenovo equips this 23.8-inch AIO with the Intel Core i3-N305, an eight-core processor that sits one step above the quad-core N100/N200 chips. The N305 uses only efficiency cores — there are no high-performance cores — but the eight Gracemont cores running at up to 3.8 GHz handle office multitasking, web browsing, and media consumption with notably better fluidity than quad-core alternatives. The 16GB of DDR4 RAM is a strong highlight at this price point, allowing you to keep dozens of browser tabs, Slack, and office documents open without hitting swap.

The three-side borderless IPS display offers 99% sRGB color accuracy, which is uncommon at this price tier. Colors appear punchy and accurate, making photo viewing and video streaming more enjoyable than on VA panels common among budget competitors. The anti-glare coating reduces reflections effectively in bright rooms. The 512GB PCIe NVMe SSD provides snappy boot and load times, and the system includes Wi-Fi 6 and Bluetooth 5.2 for modern wireless connectivity. The included keyboard and mouse are functional but received feedback about key sticking and overall build quality.

Port selection covers the essentials: two USB-A 10Gbps ports, two USB-A 2.0 ports, HDMI-out 1.4b (limited to 4K at 30Hz — fine for a secondary productivity display but not for high-refresh gaming), and a 3.5mm combo jack. The 720p webcam is serviceable for video calls but lacks the clarity of the 5MP sensors found on Dell models. The white chassis looks clean and modern, and the compact footprint makes it a natural fit for home desks where space is at a premium.

What works

  • 8-core N305 processor at a budget-friendly price
  • 16GB DDR4 RAM is generous for the tier
  • IPS panel with 99% sRGB coverage
  • Wi-Fi 6 and Bluetooth 5.2

What doesn’t

  • Included keyboard and mouse feel cheap
  • 720p webcam is mediocre for modern meetings
  • HDMI-out limited to 4K30
Storage Bundle

7. HP 21.5″ N100 AIO with Docking Hub

Intel N100128GB+256GB SD Bundle

This HP all-in-one takes an unconventional approach to storage by pairing a 128GB internal SSD with a 256GB SD card inserted into an included 8-in-1 docking hub, for a total of 384GB of usable space. The machine uses the Intel N100 quad-core processor, which is adequate for web browsing, email, and basic document editing but will show its limits under heavier multitasking. The 8GB of DDR5 RAM is enough for light workloads — expect to monitor your open tabs if you tend to keep 15+ browser windows active alongside office apps.

The 21.5-inch VA display delivers decent contrast with deep blacks, but the 1920×1080 resolution on a VA panel means narrower viewing angles than IPS — colors shift if you’re not sitting directly in front. The anti-glare treatment helps in bright rooms. The DTS-tuned speakers produce acceptable volume for system sounds and YouTube videos but lack bass and clarity for music. The adjustable stand tilts from -6° to 21°, providing decent ergonomic flexibility for a machine at this level.

The included 8-in-1 docking hub adds USB-A and USB-C connectivity along with an extra HDMI port, HDMI and SD card reader — though the SD card used for additional storage sits inside the hub, meaning the hub must remain connected to access that capacity. A wired keyboard and mouse are included in white, matching the chassis finish. Several users noted the mouse receiver lags when placed behind the monitor, so consider using the front USB ports for the wireless receiver.

What works

  • Includes 8-in-1 docking hub for extra ports
  • DDR5 RAM in an entry-level system
  • Adjustable stand for ergonomic positioning
  • Clean white aesthetic

What doesn’t

  • N100 processor struggles with multitasking
  • VA panel has narrow viewing angles
  • Storage split across internal SD and internal SSD complicates management
  • Mouse receiver positioning can cause lag
Entry-Level Quality

8. Lenovo 24″ N100 AIO – 16GB/1TB

Intel N10016GB RAM / 1TB SSD

Lenovo’s 24-inch IdeaCentre AIO prioritizes generous memory and storage over processor speed. The N100 quad-core chip is the weakest CPU in this lineup, capped at 3.4 GHz burst with 6MB cache — fine for lightweight tasks but prone to lag when running multiple heavy applications simultaneously. The saving grace is the 16GB of RAM, which compensates significantly: even though the CPU may struggle, the abundant memory means the system won’t thrash the SSD for swap space, keeping basic multitasking smoother than 8GB N100 competitors.

The 1TB SSD is the second-highest storage capacity in this roundup behind the Dell Core 7 model, giving you plenty of room for documents, photos, music, and frequent applications without worrying about filling up within the first year. The 23.8-inch FHD display produces vibrant colors and acceptable brightness, though the panel type is unspecified — user feedback describes “rich color” and “high evolution clarity,” suggesting a decent quality display with good contrast. The 5MP AI camera with IR supports Windows Hello and performs better than the 720p cameras on other entry-level models.

Wireless connectivity covers Wi-Fi 6 and Bluetooth 5.2, and the Harman audio-enhanced speakers provide better-than-average sound for video calls and casual media consumption. The stand supports a tiltable design for basic ergonomic adjustment. The main shortcoming is the N100 processor itself — if your workflow involves more than ten browser tabs and office documents, you will feel the CPU hit its ceiling during peak demand. For a student or a user whose needs are strictly email, browsing, and streaming, this configuration offers the most storage and RAM for the least processing power.

What works

  • 16GB RAM is excellent for an entry-level system
  • 1TB SSD provides generous local storage
  • 5MP IR camera with Windows Hello
  • Harman speakers outperform typical budget audio

What doesn’t

  • N100 CPU bottlenecks performance
  • No USB-C port for modern accessories
  • Display panel type not confirmed as IPS
Budget Baseline

9. HP 21.45″ N200 AIO – 8GB/512GB

Intel N200VA FHD Display

The HP 22-dg0340 is the entry point to the all-in-one segment, built around the Intel N200 processor — a quad-core chip with a 3.7 GHz max turbo and 6MB cache that improves slightly over the N100 in sustained workloads but remains firmly in the low-power segment. The 8GB of RAM is the bare minimum for Windows 11 in 2025: the operating system plus a browser with a few tabs will consume roughly 5-6GB, leaving limited headroom for additional applications. The 512GB NVMe SSD provides fast boot times and adequate storage for documents and essential software.

The 21.45-inch VA panel produces deeper blacks than IPS but narrower viewing angles — fine for a single user sitting directly in front but less ideal for shared viewing. The FHD resolution at this screen size delivers a comfortable 102 PPI density for text clarity. HP includes DC Dimming technology to eliminate flicker at all brightness levels, which genuinely reduces eye strain during extended sessions. The manual camera shutter provides hardware-level privacy, and AI-noise reduction helps filter out background noise during video calls. The dual 2W speakers are adequate for system sounds but lack bass and volume for music or movies.

Connectivity includes a single USB-C 5Gbps port, two USB-A 5Gbps ports, two USB-A 2.0 ports for low-speed peripherals, HDMI, and an RJ-45 Ethernet port. Wi-Fi 6 and Bluetooth 5.3 support modern wireless standards. HP uses recycled plastics in construction and holds EPEAT Gold and ENERGY STAR certifications. Buyer feedback is generally positive, noting easy setup and a clean appearance, though some reported a defective mouse after a few weeks. At this price, the machine works well for a student or light home user whose daily tasks stay within email, web, and document editing.

What works

  • Lowest entry price into the AIO category
  • 512GB NVMe SSD for fast boot times
  • DC Dimming eliminates screen flicker
  • Uses recycled plastics and has green certifications

What doesn’t

  • 8GB RAM limits multitasking headroom
  • VA panel with narrow viewing angles
  • Included mouse reported as defective by some users
  • N200 processor is limited for anything beyond basics

Hardware & Specs Guide

Intel N-Series vs Core Processors

The Intel N100/N200 chips are quad-core processors built on the Alder Lake-N architecture using only Gracemont efficiency cores with no performance cores. They have a 6W thermal design power and are designed for passive or low-noise cooling, making them suitable for basic web tasks. The i3-N305 upgrades to eight efficiency cores but still lacks performance cores. True desktop-grade performance comes from Core U-series processors like the i5-13420H, which combines 4 high-performance P-cores with 4 efficiency E-cores and can draw 28W or more, providing 2-3x the multi-threaded performance of N-series chips. If you regularly run spreadsheet calculations, photo editing, or have 20+ browser tabs open, the Core U-series is the minimum starting point.

VA vs IPS Panel Technology

VA panels offer higher native contrast ratios — typically around 3000:1 to 4000:1 — which produces deep blacks and excellent shadow detail in dark scenes. The trade-off is color shift and brightness drop-off when viewed from angles beyond 30 degrees off-center. IPS panels achieve approximately 1000:1 contrast but maintain color and brightness consistency up to 70-80 degrees off-axis, making them better for collaborative viewing and color-accurate work. IPS panels with 99% sRGB coverage are standard on mid-range and premium all-in-ones, while VA panels appear mostly on entry-level models. For photo editing or any work where color accuracy matters, choose an IPS panel.

RAM Configurations: DDR4 vs DDR5

DDR5 RAM offers double the maximum data rate of DDR4 — starting at 4800 MT/s versus 3200 MT/s for DDR4. In all-in-one computers that use integrated graphics, faster system memory directly improves GPU performance because the integrated graphics card shares system RAM for video memory. A DDR5-equipped AIO will show smoother frame rates in casual gaming and faster rendering in GPU-accelerated tasks. DDR5 also operates at lower voltage (1.1V vs 1.2V), which slightly reduces power consumption and heat. However, DDR5 modules are currently more expensive, and the real-world benefit for basic office work is marginal — the main advantage appears in multitasking and creative applications.

Storage Types and Transfer Speeds

NVMe SSDs using PCIe Gen 3 or Gen 4 achieve sequential read speeds between 3,500 MB/s and 7,000 MB/s, compared to SATA SSDs that max out around 560 MB/s. The difference is tangible: Windows boots in 10-15 seconds on an NVMe drive versus 25-30 seconds on SATA, and large application files load noticeably faster. Some budget all-in-ones attempt to expand storage via SD card slots or USB hubs, but SD cards have much lower random IOPS performance than genuine SSDs and are not suitable for running active applications. Always prioritize a pure NVMe SSD as the primary drive; external storage is fine for media archives but should not be used for active operating system or application workloads.

FAQ

Can an affordable all-in-one computer be upgraded with more RAM later?
Most all-in-one computers have their RAM soldered directly to the motherboard or use SO-DIMM slots that are accessible through a removable panel. N-series systems from HP and Lenovo often have the RAM soldered, meaning you must choose the correct capacity at purchase. Dell’s 24 and 27 models tend to use SO-DIMM slots that can be upgraded, though accessing them may require removing the rear cover. Always check the specific product’s service manual before buying if future upgradability matters to you.
Can I use an all-in-one computer as a monitor for a gaming console?
Only all-in-one computers with an HDMI-in port can function as standalone monitors. The Lenovo ThinkCentre 27″ and Lenovo IdeaCentre 27″ listed in this guide include HDMI-in ports alongside HDMI-out, meaning you can connect a PlayStation, Xbox, or Nintendo Switch to the display while the computer itself is turned off. Most other models only have HDMI-out, which sends the computer’s video signal to an external monitor but does not accept external video input. Confirm the presence of “HDMI-in” in the specifications if this feature matters to you.
Does an all-in-one computer support a second external monitor?
Yes, nearly every all-in-one includes at least one HDMI-out or DisplayPort-out port that can drive a second monitor at up to 4K resolution. The Dell 24 and Dell 27 models, as well as the Lenovo ThinkCentre, all support external displays. Models with HDMI 2.1 can drive high-bandwidth 4K at 60Hz, while older HDMI 1.4b ports are limited to 4K at 30Hz. If you plan to run two screens, make sure the AIO’s output port matches your monitor’s input capability.
How long will an affordable all-in-one computer last for typical home use?
With a Core i3-N305 or better processor and 16GB of RAM, you can expect 3-5 years of comfortable performance for web browsing, office applications, and streaming media. N-series-based systems with 8GB of RAM will likely feel slow within 2-3 years as web apps continue to increase memory and processing demands. The all-in-one form factor is more difficult to repair or upgrade, so choosing a model with 16GB RAM and an SSD larger than 256GB from the start is the best way to extend usable life.
Are the webcams on budget all-in-ones good enough for professional video calls?
Entry-level models typically include 720p cameras that produce soft, grainy images in anything less than bright, even lighting. Mid-range and premium models like the Dell 24 and Dell 27 with 5MP IR sensors produce significantly sharper video, better low-light performance, and support Windows Hello facial recognition. If you take frequent professional video calls, prioritize a model with at least a 2MP or 5MP camera — the difference in perceived professionalism on the other end is substantial.

Final Thoughts: The Verdict

For most users, the best affordable all in one computer winner is the Lenovo ThinkCentre 27″ i5-13420H because it pairs a true eight-core processor with 16GB of DDR5 RAM, a smooth 100Hz IPS panel, and the rare HDMI-in port that doubles the display as a monitor for a console or streaming stick. If you need a touchscreen for interactive workflows or professional meetings, grab the Dell 24 Touch Core 5 120U. And for an entry-level system that maximizes storage and RAM over raw CPU speed, nothing beats the Lenovo 24″ N100 AIO with 16GB RAM and a 1TB SSD.
