The 5 Best PC Cases Under $100

A great PC case does more than hold your components together. It shapes airflow, dictates how much hardware you can fit, determines how easy the build process will be, and sets the visual tone of your entire setup.

The good news is that the sub-$89.99 segment has never been more competitive: builders today can find cases with pre-installed ARGB fans, tempered glass panels, USB-C front I/O, and thoughtful cable management channels without spending a premium.

Whether you are putting together a first gaming rig, upgrading an aging enclosure, or building a clean workstation on a tight budget, there are genuinely strong options available from brands like Corsair, Lian Li, and MUSETEX.

At REMOVU, we researched the crowded PC case market by analyzing manufacturer specifications, synthesizing expert review consensus from across the enthusiast community, and weighing verified buyer feedback to surface the options that consistently deliver on airflow, build quality, and long-term usability.

Every pick in this roundup represents the best balance of value and capability we found in the budget segment. Scroll down to see our ranked top picks.

PC Cases Under $100 Buying Guide

Choosing the right PC case at this price tier means balancing several competing priorities. A case that looks stunning in photos can frustrate you during the build if cable routing is cramped or fan mounts are poorly positioned.

The sections below cover the criteria that matter most, drawn from the specifications and builder experiences we evaluated across every model in this roundup.

If you want a broader view of the market beyond the budget segment, our guide to PC cases for every build and budget is a useful starting point.

Form Factor and Motherboard Compatibility

Every case in this roundup is an ATX mid-tower, which is the most versatile form factor for the overwhelming majority of desktop builds.

ATX mid-towers support standard ATX motherboards as well as the smaller Micro-ATX and Mini-ITX form factors, giving you flexibility if you decide to downsize your motherboard in the future.

If you already know you want a compact build, a Mini-ITX case may serve you better, but for most builders an ATX mid-tower is the safest and most future-proof choice.

Before committing to any case, verify that your motherboard standoff layout matches. Most ATX mid-towers include pre-installed standoffs for ATX boards and provide tools or guides for repositioning them for smaller form factors.

Check the product page for the specific form factors supported and whether the manufacturer includes the hardware needed for each configuration.

Airflow and Fan Configuration

Airflow is arguably the single most important performance factor in a PC case. A case with poor airflow will raise component temperatures, which reduces performance and longevity of your CPU and GPU.

Look for cases with a mesh or perforated front panel rather than a solid acrylic or steel front, as mesh panels allow significantly more intake air to reach your components.

The Corsair 4000D RS ARGB is a standout example of a case engineered specifically around high-airflow principles at this price point.

Pay close attention to how many fans come pre-installed and where they are positioned. Front intake fans and rear exhaust fans create a straightforward positive-pressure or balanced airflow path.

Cases like the MUSETEX Y6 with seven pre-installed ARGB fans offer impressive out-of-the-box airflow without requiring additional fan purchases. Also check how many additional fan mounts are available if you want to add a radiator later.

GPU Clearance and Radiator Support

Modern graphics cards have grown substantially in both length and thickness. A case that cannot accommodate a long or triple-slot GPU will force you into frustrating compromises. Check the manufacturer-listed maximum GPU length for any case you consider.

The Lian Li Vector V100, for instance, supports GPUs up to 420 mm in length, which covers virtually every current consumer card.

Many cases in this segment also include a GPU support bracket to prevent GPU sag, which is a welcome inclusion that is not always present at this price.

Radiator support matters if you plan to use or upgrade to an all-in-one liquid cooler. Cases that support 360 mm radiators in the front or top give you the most flexibility for cooling a high-core-count CPU.

If your build will rely on a large air cooler instead, check the maximum CPU cooler height the case supports, as some compact mid-towers cap clearance below what larger tower coolers require.

Pairing a spacious case with a capable CPU cooler is one of the most effective ways to keep thermals in check.

Cable Management and Storage

A tidy build is not just aesthetic: good cable routing actually improves airflow and makes future upgrades far less painful.

Look for cases that offer a dedicated PSU shroud, multiple cable routing cutouts with rubber grommets, and a generous amount of space behind the motherboard tray (typically 20 mm or more).

Velcro straps, cable tie mounts, and pre-routed paths for 24-pin and CPU power cables are small features that add up to a much smoother build experience.

Storage compatibility is worth checking if you have multiple drives. Most cases in this segment support at least two 3.5-inch drive bays and two or more 2.5-inch mounts.

If you are building a storage-heavy system or plan to add drives over time, prioritize cases with at least three or four total drive mounting points. Budget for your SSDs and hard drives accordingly when planning your layout.

Front Panel I/O and Connectivity

Front panel connectivity is easy to overlook until you need it.

USB-C on the front panel has become an increasingly common and genuinely useful feature, particularly for connecting modern peripherals, external drives, and smartphones quickly without reaching around to the back of the case.

All five models in this roundup include USB-C front I/O, which was a key consideration in our selection. Make sure your motherboard has the corresponding USB-C header if you want to use this port.

Beyond USB-C, look for at least two USB-A 3.0 ports and a combined audio/microphone jack.

Some cases in this price range include a dedicated display or LED control button on the front panel, which can be a convenient alternative to software-based RGB control.

Confirm that the power button and LED headers match your motherboard’s layout before finalizing your choice.

Tempered Glass and Build Quality

Tempered glass side panels have become a standard feature even at budget price points, and the cases in this roundup reflect that shift.

The key differentiator is panel coverage: some cases offer a single side panel window, while others like the MUSETEX Y6 provide a 270-degree full-view design that exposes the top, front, and side of the build simultaneously.

Full-view panels create a more dramatic showcase effect but can also highlight messy cable runs, so clean cable management becomes even more important.

Steel gauge and panel fitment quality vary noticeably at this price tier. Thicker steel (typically 0.8 mm or above) reduces flex and produces a more solid feel when closing panels.

Hinged side panels and tool-free access are convenient quality-of-life features that experienced builders appreciate. Dust filters on intake areas are another practical consideration, particularly for setups in dustier environments.

Look for removable, washable filters at the front, bottom, and top vents.

Frequently Asked Questions

Do I need to buy additional fans for these cases?

Most cases in this roundup come with three to seven pre-installed fans, which is sufficient for a standard gaming or productivity build. The MUSETEX models are particularly generous in this regard.

If you plan to add a large radiator or push high-end components hard, you may want to add one or two extra fans to additional mount positions, but out of the box these cases are ready to use without immediate fan upgrades.

Are these cases compatible with liquid cooling?

Yes, all five cases support at least a 240 mm radiator, and several support up to 360 mm.

The Lian Li Vector V100 and the Corsair 4000D RS ARGB offer the most flexible radiator mounting options, accommodating 360 mm radiators in the front position, which is ideal for high-performance all-in-one coolers.

Always cross-reference the case specifications with your cooler’s mounting requirements before purchasing.

What is the difference between a mesh front panel and a glass front panel?

A mesh or perforated front panel allows significantly more air to pass through to front-mounted intake fans, which results in lower component temperatures under load.

A solid glass or acrylic front panel restricts airflow and can cause temperatures to rise noticeably in demanding workloads. If thermal performance is a priority, a mesh front case like the Corsair 4000D RS ARGB is the better choice.

If you prefer a cleaner aesthetic and your build is not heavily loaded, a glass front panel is a reasonable trade-off.

Can I use a full-size ATX power supply in these cases?

All five cases in this roundup support standard ATX power supplies. Each case includes a PSU shroud that conceals the power supply and associated cabling for a cleaner interior appearance.

Check the maximum PSU length listed in the specifications if you are using an extended ATX or modular power supply with thick cables, as very long units can occasionally conflict with cable routing in some mid-tower layouts.

Our category page on power supplies can help you find a compatible unit.

How important is USB-C on the front panel?

USB-C on the front panel is increasingly useful as more peripherals, portable SSDs, and smartphones adopt the connector. All five cases here include a front USB-C port, which sets them apart from older budget models.

To use the port, your motherboard needs a USB-C (USB 3.2 Gen 1 or Gen 2) internal header. Check your motherboard’s specification sheet before assuming the port will be functional out of the box.

A compatible ATX board will almost always include this header in the current generation.

Are budget PC cases difficult to build in?

Build experience varies more by design than by price. Some budget cases include thoughtful features like tool-free drive trays, pre-routed cable channels, and hinged side panels that make the process smooth even for first-time builders.

Others cut costs in ways that create frustration, such as sharp interior edges, limited cable management space, or awkward fan connector placement.

Reading verified buyer reviews specifically about the build process, rather than just the finished look, is one of the most reliable ways to gauge how builder-friendly a case actually is in practice.
