You want a PC case under $100 that doesn’t force you to pick between good airflow and good looks. The best options in this price range now include several ARGB fans (colorful, customizable LED fans) pre-installed, tempered glass panels (shatter-resistant glass that shows off your parts), and enough room for a large GPU and a 360mm radiator (a big liquid-cooling unit) — so you get both style and cooling without extra cost.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
We’ve sorted through the crowded mid-tower market to find the cases that deliver real airflow, easy builds, and strong value. pc case under $100 is your shortcut to a smart, cooling-first case choice.
Our Picks at a Glance
How To Choose The Best PC Case Under $100
Before you pick a case, check the size of your graphics card, your CPU cooler, and your power supply. These three parts dictate whether your build fits comfortably inside a mid-tower or needs extra breathing room.
Fan Count and Airflow
Pre-installed fans are the biggest value driver in this price tier. A case with seven ARGB fans included saves you from buying extras separately, which adds up quickly. Look for a mix of reverse-blade fans on the side and bottom, since they pull air in without showing off their frames.
GPU and Radiator Clearance
Modern graphics cards are long, so you need to check your GPU’s length against the case’s spec. Look for a case that supports GPUs up to 400mm or more — that gives you room to install without squeezing, and it also fits most high-end GPUs and AIO coolers (all-in-one liquid coolers) that require 360mm radiator support.
Build Quality and Layout
Tempered glass panels and a dual-chamber layout separate the power supply from the main components, which makes cable management easier and looks cleaner. Check that the side panels use a tool-less or thumbscrew mechanism so you can open the case quickly when you upgrade parts later.

In‑Depth Reviews
1. MONTECH XR Panoramic High Airflow ATX PC Case
The crowd favorite that pairs panoramic glass with serious airflow — a balanced choice.
The MONTECH XR is the pick that wins people over with its combination of tempered glass and real cooling performance. It ships with 3 pre-installed ARGB fans spinning up to 1500 RPM — two reverse-blade on the side and one regular on the rear — so you get bright, vibrant lighting without needing to buy extra fans. The tempered glass enclosure is supported by filters on the top, bottom, and side panels, which keeps dust out while the air flows through.
This case holds its own against pricier rivals on component support. It accommodates a 360mm radiator at the top and handles high-end GPUs like the 40 series, with clearance for cards up to 420mm. Owners highlight easy cable routing, a clear manual, and stable temperatures with quiet fans. The one recurring note is that the side panel fits tight and needs a little pressure to close, and an occasional glass panel arrives with a scratch.
What Wins People Over
- Spacious ATX interior with excellent cable management room
- Pre-installed reverse-blade ARGB fans are bright and quiet
- Tool-less drive bays make the first build easy
Worth Knowing
- Side glass panel fits tight and needs firm pressure
- One exhaust fan may run warm with a high-power GPU — add a top fan
Reach for this if: you want a roomy, good-looking case with effective cooling from the start at a value price.
Think twice if: you plan to run a very hot build and don’t want to add a couple of extra fans yourself.
2. Lian Li V100-ATX Mid-Tower PC Case
A premium-feeling chassis whose quality is the most-praised detail by owners.
The Lian Li V100 is the case that makes you feel like you spent more than you did. Owners most often praise the build quality, with the clean appearance a close second. It arrives with 4 pre-installed PWM-controlled 120mm ARGB fans that reach 1800 RPM, plus an integrated 26-LED ARGB strip that syncs with your motherboard software for full-spectrum control.
Inside, it supports ATX, Micro-ATX, Mini-ITX, and back-connect motherboards, with room for GPUs up to 420mm and CPU coolers up to 178mm. The tool-less side panels pop off easily for quick access, which experienced builders appreciate. The internal bays total 4 — the MONTECH XR above has 3 bays — giving you more mounting spots for drives. The fan noise is rated between 26.5 and 30.8 dBA, so it stays quiet during normal use, though sound isolation from outside noise is not its strength.
Solid all-arounder: The V100 delivers a sturdy, clean build that rivals cases costing more. The trade-off is weak sound isolation and intake fan wires routed through the body, which some owners reroute for a cleaner finish.
Best if: you prioritize build quality and aesthetics and want a case that’s genuinely easy to work in.
Look elsewhere if: you need maximum acoustic damping in a noisy room.
3. FOIFKIN F1 PC Case
A dual-chamber case that arrives mostly pre-assembled with six fans installed.
The FOIFKIN F1 is built around a dual-chamber design that separates your hardware from the power supply and drives, which helps thermals and keeps cables tidy. It comes with 6 pre-installed 120mm ARGB PWM fans — five reverse and one forward — so the interior is fully lit the moment you open the box. Owners note quiet fans, strong airflow, and a mostly pre-assembled build with working ports and wiring.
It fits ATX, M-ATX, and ITX motherboards, supports GPUs up to 400mm, and accommodates PSUs up to 200mm. The front I/O includes a Type-C 3.0 port, a USB 3.0, two USB 2.0, and audio jacks. It’s wide enough for large CPU coolers, and the dual glass walls give you a full view of the interior. The catch is that older motherboards may need a 12V-to-5V ARGB converter to control the lighting, and the glass panels take a bit of effort to pry off.
Smart layout: The dual-chamber layout and included six fans make this an exceptional value. Just plan for the ARGB converter if your motherboard isn’t new, and keep a screwdriver handy for the snug glass panels.
Reach for this if: you want a fully lit, easy-to-build case with a clean hidden-PSU look.
Consider another if: your motherboard is older and you want plug-and-play RGB control without adapters.
4. MUSETEX Y6 PC Case
A lighting showpiece with seven Infinity Mirror fans and a 270-degree glass view.
The MUSETEX Y6 is for builders who want their PC to be the centerpiece of the room. It ships with 7 pre-installed 120mm Infinity Mirror ARGB fans — three reverse on the side, three reverse on the bottom, one forward on the back — that produce smooth gradient rainbow light bands. The 270° fully transparent dual tempered glass panels give a wider view than most cases in this range.
Beyond the looks, it supports ATX, Micro-ATX, and Mini-ITX motherboards, with GPU clearance up to 410mm, CPU cooler height up to 160mm, and top mounting for a 360mm liquid cooler. Owners praise the build quality and looks, and the seven included fans eliminate extra purchases. The honest catch is cable management: the fan wires are short and ribboned, so you’ll want to plan your wiring before installing, and a full ATX board limits bottom cable space.
Show-Stopper Looks
- Seven Infinity Mirror fans with silky color transitions
- 270-degree glass panels showcase your hardware and collectibles
- Fans are quiet and the airflow keeps temps stable
Planning Required
- Short fan cables mean careful wiring before install
- Full ATX boards reduce bottom cable space — best for micro ATX
Buy it for: the most striking exterior in this price tier, especially for a white-themed build.
Think twice if: you want individual RGB control per fan — the ribboned design limits customization.
5. Antec C5 ARGB Mid-Tower ATX PC Case
A smooth glass fish-tank design with a built-in fan and RGB controller hub (a hub that manages your fans and LED lighting in one place).
The Antec C5 nails the dual-chamber fish-tank look (a case with two separate compartments for a clean interior) without a huge price tag. It comes with 7 pre-installed ARGB PWM fans (colorful, speed-controlled fans), including 6 reverse-blade models that push air the opposite way for better flow, plus a built-in ARGB and PWM fan controller. Owners praise the looks and report no thermal throttling under gaming load, even without top fans. The 270° smooth tempered glass on the front and side panels gives you an unobstructed view of your build, so you can show off every component.
The dual-chamber design keeps the interior spacious, with room for large air coolers — one owner fit a Phantom Spirit 120 SE with space to spare — and supports 360mm radiators. It also handles back-connect motherboards for cleaner routing. The recurring gripes are the long rear fan cables that fold easily and an angular front panel with an internal RGB strip. Assembly experiences are mixed, so it rewards builders who take their time.
Controller included: The built-in fan and RGB hub simplifies setup, while the wide layout aids cable management. The long rear fan cables are the main annoyance — tuck them carefully.
Buy it for: the smooth glass look and the convenience of a built-in fan controller — you won’t need to buy a separate hub to manage your fans and lights.
Take your time if: you’re a first-time builder — the assembly isn’t hard, but it demands patience.
6. Lian Li Lancool 207 Compact ATX RGB Gaming Case
A compact chassis with a clever layout that pushes air straight under the GPU.
The Lancool 207 is the case that rethinks the conventional layout. It mounts the PSU at the front with an adapter cable and positions two bottom fans directly under the GPU for tune cooling. It ships with 4 fans: two 140x140x30mm ARGB fans at the front with infinity mirror centers reaching 1900 RPM, and two 120x120x25mm PWM fans with 11 blades each under the GPU reaching 1950 RPM.
Owners praise the layout and ease of building, noting lower CPU and GPU temperatures. The included GPU anti-sag bracket is adjustable and keeps your graphics card secure. It also has a front USB Type-C port. The honest trade-offs: the front fans can produce a resonant hum that some fix with rubber gaskets, and the PSU length support is capped at 160mm, so you’ll need a modular or shorter unit.
Smart Engineering
- Dual bottom fans cool the GPU directly
- Adjustable anti-sag bracket included
- Compact footprint with room for components
Layout Limits
- Front fans may hum — rubber gaskets help
- PSU length capped at 160mm, so plan your power supply
Best for: builders who want a compact case with serious GPU cooling and a clean cable-free look.
Not ideal if: you own a long non-modular power supply that exceeds 160mm.
7. Corsair 3500X RS ARGB Panoramic Mid-Tower PC Case
A wraparound glass showcase that’s validated for reverse-connection motherboards.
The Corsair 3500X is for builders who want a panoramic view with a trusted brand name. It comes with 3 pre-installed RS120-R ARGB fans and supports motherboard form factors from Mini-ITX up to EATX, giving you more board options than most cases this size. The wraparound glass aesthetic delivers the view, while side, roof, and PSU fan mounting points let you scale up to 10x 120mm fans without sacrificing cooling.
Owners praise the quality and looks, reporting 15-20°C lower gaming temps than a prior M-ATX build. It’s compatible with Corsair Shift PSUs and pairs well with Corsair Nautilus AIO coolers. It’s also validated for reverse-connection motherboards like ASUS BTF, MSI Project Zero, and Gigabyte Project Stealth, so cables can hide behind the board. The catch is that cable management gets mixed opinions — it works but takes time — and durability opinions are split, so it’s a case to handle with care.
Great view, great value: The 3500X offers a premium feel and strong cooling for the price. It’s not the easiest for complex cable routing, so budget some time for the wiring.
Reach for this if: you want a wide-open glass view and plan to use a reverse-connection motherboard.
Be cautious if: you want easy cable management — this one rewards patience.
Understanding the Specs
Fan Count and Type
More fans usually mean better airflow, but the type matters too. Reverse-blade fans pull air in without showing their support frames, which looks cleaner on the side and bottom. PWM fans let your motherboard control their speed automatically, so they stay quiet at idle and ramp up under load.
GPU and Radiator Clearance
Graphics cards have grown in length, so check the maximum GPU clearance before buying. A 360mm radiator support means you can mount a three-fan liquid cooler at the top, which is the standard for high-end CPUs. Measure your parts against these numbers to avoid a build that doesn’t fit.
