Best Compact PC Cases for 2026: Top Small-Form Picks

The V100 Mini Micro-ATX PC gaming case comes pre-equipped with four ARGB PWM cooling fans, featuring three side intake fans and one rear exhaust fan to establish immediate thermal airflow. Its compact chassis supports up to nine 120mm fans total, alongside top radiator rails capable of mounting 360mm AIO liquid coolers for high-performance processor cooling. Builders should note that 280mm AIO coolers are not supported due to motherboard clearance constraints. This optimized ventilation design draws cool air across internal components, keeping temperatures low during heavy gaming workloads.

Featuring a pillarless 270-degree dual tempered glass panel design, this computer chassis offers a clear view of your internal hardware components and customized lighting effects. The spacious interior accepts Micro-ATX and ITX motherboards, with clearance for large graphics cards up to 415mm long. An included height-adjustable anti-sag bracket anchors heavy horizontal GPUs securely to prevent slot strain. Dedicated cable routing channels and tie-down points behind the power supply shroud keep wiring organized and hidden for a clean build presentation across your gaming setup.

When planning your PC build inside the V100 Mini, verify motherboard form factor compatibility, as standard full-size ATX boards are not supported. The 5-slot expansion layout is optimized for single graphics card configurations rather than dual-GPU setups. Placing the chassis on a firm desk surface ensures proper airflow through bottom intake vents, while removable dust filters simplify routine maintenance. This mini-tower case provides an ideal foundation for gamers building a compact yet powerful desktop PC build for daily gaming activities.

The MiniArt 4 is a 24.5-liter Micro ATX case with full-mesh front and side panels and a front-mounted power supply layout. It ships with three 120mm fans pre-installed - two reverse-flow intake fans and one standard fan - with mounting for up to five fans total across the chassis for stronger airflow.

• Form factor: Micro ATX, 24.5L
• Radiator support: Up to 240mm
• Panels: 1.2mm fine mesh, tool-free top and side
• Cable routing: 25mm main channel, 8mm behind tray

A walnut wood logo badge on the front sets it apart from the all-plastic and metal cases common in this size class.

Component clearance in the MiniArt 4 is interdependent: the front-mounted PSU bay accepts supplies up to 150mm long (without cables), and GPU length scales inversely with PSU length. Supplies of 140mm or shorter free up space for graphics cards up to 330mm, while longer supplies cap GPU length at 280mm. A 10A extension cable is included for the front-mount PSU layout.

• PSU length limit: 150mm (excluding cables)
• GPU clearance: 330mm with 140mm or shorter PSU, 280mm with longer PSU
• Included: 10A PSU extension cable

Measure both your power supply and graphics card before ordering, since exceeding either limit will prevent the side panel from closing properly.

Vertical airflow is the design focus, with multi-zone mesh vents across the top, side and front panels feeding up to five fans plus 240mm radiator support. The layout is built to pull air in through the mesh sides and exhaust it through the top, keeping a Micro ATX build cool without the case growing much beyond 24.5 liters.

• Fan support: up to 5x120mm
• Pre-installed: 2 reverse-flow + 1 standard 120mm fan
• Radiator support: 240mm at the top or front

Because the panels favor open mesh over sealed dust filters, builds in workshop or pet-heavy rooms will need more frequent interior cleaning to keep the fans and radiator fins clear.

A micro-ATX chassis measuring 18.11 by 8.07 by 13.78 inches for a total of around 33 litres, compact without resorting to the compromises of a true mini-ITX box.

• Graphics cards up to 338 mm long
• Standard ATX power supplies up to 180 mm, not SFX-only
• Radiators up to 280 mm and 360 mm
• Room for custom liquid cooling and a spread of storage devices
• 32 mm gap behind the extended motherboard tray for cabling

Taking a full ATX power supply is the specification that separates this from most small cases, because it means an existing unit can move straight across instead of being replaced with a compact one. The 338 mm graphics limit covers the majority of triple-fan cards, though the very longest flagship models still need measuring first.

The panels are the cooling strategy. The mesh is drilled with over 57,000 holes of 1.5 mm each, which passes far more air than a pattern of fewer, larger openings while still holding back the coarse dust that clogs a fin stack.

• Support for up to six fans across the available mounts
• 280 mm and 360 mm radiator positions
• Two 120 mm bottom mounts sit behind a removable dust filter
• One fan comes pre-installed, so the remaining mounts are yours to populate

Plan intake and exhaust deliberately in a 33-litre case. Small volumes heat up quickly when a hot graphics card and a tower cooler share the space, so a slight positive pressure through filtered intakes keeps both temperatures and dust under control.

Two design decisions make this an easy first small-form-factor build. The side panels use a clip mechanism with no screws, so they come off in seconds and stay put in transit, and the motherboard tray is extended with cut-outs placed where the cables actually need to pass.

• 32 mm of routing depth behind the tray, generous for a case this size
• Tool-free panels mean no thumbscrews dropped behind a desk
• Bottom dust filter pulls out for cleaning without dismantling anything
• Covered by a 2-year warranty

Order of work matters more in a small case: fit the power supply and route its cables first, then the cooler, then the motherboard, and leave the graphics card until last. The mesh panels also mean the interior reads in silhouette rather than on full display, so tidy cabling here is about airflow more than looks.

The JONSBO JONSPLUS Z20 Black Micro-ATX Mini Tower PC Case provides essential hardware performance for custom PC builds and workstation upgrades. Engineered to manage demanding electrical or thermal workloads, this model incorporates JONSBO JONSPLUS Z20 Mini Micro-ATX PC with Detachable Carrying together with Thick to 2mm integrated bent steel panels (panel top panel)Complemented.

At 17.4 x 7.63 x 12 inches, the A3-mATX packs a 26.3 liter volume that still clears graphics cards up to 415mm long. Steel mesh panels on the side and top are designed specifically to move air through high-TDP GPUs and radiator setups rather than trap heat inside a closed shell.

• 26.3 liter internal volume in a compact mATX/ITX footprint
• GPU clearance up to 415mm, enough for most full-size graphics cards
• Mesh side and top panels prioritize airflow over a fully enclosed look

The compact size makes it a strong fit for small-form-factor builds that still need room for high-end hardware, rather than a true mini-ITX-only chassis.

The chassis accepts mATX and ITX motherboards across 4 expansion slots, and supports front or side PSU mounting compatible with ATX, SFX, SFX-L and LIAN LI's own EDGE power supplies. This flexibility lets builders orient the power supply to whichever side offers better cable routing for their layout.

• mATX and ITX motherboard support across 4 expansion slots
• Front or side PSU installation compatible with ATX, SFX, SFX-L and EDGE units
• Modular internal layout supports repositioning parts as the build evolves

Full ATX motherboards are not supported given the 4-slot limit, so builders should confirm their board size before purchase.

The case supports a 360mm radiator alongside up to 10 individual 120mm fans, giving serious headroom for liquid cooling in a small chassis. No fans are included, so cooling has to be assembled separately to match the intended thermal load.

• 360mm radiator support for all-in-one liquid coolers
• Up to 10 x 120mm fan mounting points across the chassis
• No fans included, plan to add case fans or an AIO separately

The walnut wood front panel and modular structure are built for builders who plan to revisit the internal layout over time, rather than a fixed one-time build, making later upgrades more straightforward than in a rigid steel-only case.

The SG13B keeps a full-size build inside an 11.5-liter shell measuring 8.74 inches deep, 11.22 inches wide, and 7.13 inches tall. It is built around a Mini-ITX or Mini-DTX motherboard paired with a standard ATX power supply, so builders are not locked into small-form-factor-only components for the PSU.

• 11.5-liter internal volume in an 8.74"D x 11.22"W x 7.13"H steel body
• Front panel accepts expansion cards up to 10.5 inches long
• Storage holds one 3.5-inch and one 2.5-inch drive together, or three 2.5-inch drives alone

The steel chassis with a mesh or solid front panel option keeps the footprint small enough for a desk or shelf while still fitting drives and cards sized for a full desktop build rather than a laptop-class mini PC.

Cooling in the SG13B is configurable rather than fixed. Builders can run the case with no active front cooling, add a single 120mm or 140mm fan to the front panel, or mount a 120mm/140mm single-fan all-in-one liquid cooler in the same location.

• Supports one 120mm or 140mm fan, or a matching single-fan AIO cooler, in the front panel
• Standard ATX PSU mount clears CPU air coolers up to 61mm tall
• A 140mm-class fan takes about 1 inch of the 10.5-inch card space, leaving roughly 9.5 inches for a graphics card

Because the front bay does double duty for fans, coolers, and card clearance, the choice of cooling method directly affects how long a graphics card can be before it interferes with airflow components.

The case ships set up for a standard ATX power supply and can fit units up to 150mm long, which is the configuration that limits CPU cooler height to 61mm. Builders who want more clearance can switch to an SFX power supply using the separately available SilverStone PP08B ATX-to-SFX adapter.

• Stock ATX PSU mount fits power supplies up to 150mm long
• Switching to SFX with the PP08B adapter frees up an additional 21mm of internal space
• That extra space raises CPU air cooler clearance from 61mm to 82mm

This means the practical cooler height in the SG13B depends on which power supply format is installed, so builders planning a taller air cooler should plan for the SFX adapter rather than assuming the stock ATX clearance will fit.

The O11Vision uses a patented three-panel tempered glass design across the front, top and left side, aimed at showing off internal components from nearly every angle rather than hiding them behind solid steel. The top mesh panel supports mounting a 360mm AIO liquid cooler, giving room for higher-capacity cooling than smaller mid towers allow.

• Tempered glass front, top and left panels
• Top mesh support for up to a 360mm AIO radiator
• External dimensions of 17.6 x 11.3 x 17.57 inches

Because three sides are glass rather than vented steel, airflow planning benefits from the top mesh panel doing more of the intake or exhaust work.

This case supports back-connect motherboards, a layout where power and data connectors sit on the rear of the board rather than the front edge, letting cables route behind the motherboard tray for a cleaner front-facing build. Built from SECC steel, the frame is rigid enough to support standard ATX boards and larger graphics cards.

• Back-connect motherboard support for hidden cable routing
• SECC steel chassis frame
• ATX mid tower form factor

Buyers using a standard front-connector motherboard will still fit the case, but the rear-cable-routing benefit is only realized with a back-connect compatible board and matching power supply cables.

An innovative second chamber conceals AIO cooler tubing when the radiator is mounted on the side, hiding tubing runs that would otherwise cross the main build area on view through the glass panels. Combined with the back-connect support, this is aimed at builders prioritizing a clean, cable-free look through the glass.

• Second chamber hides AIO tubing runs from side-mounted radiators
• Developed in collaboration with the PCMasterRace community
• Mid tower ATX sizing supports most standard component layouts

Because the layout is optimized around visible glass panels and hidden cabling, builders who prefer a fully closed, sound-dampened case may find this design leans more toward display than acoustic isolation.
