Building a compact PC doesn’t mean sacrificing performance or style. Mini ITX cases let you create a powerful computer that takes up less desk space and fits into smaller areas. These small cases work with Mini ITX motherboards, which are only 6.7 inches square, making them perfect for people who want a capable machine without the bulk of a traditional tower.
A good Mini ITX case needs to balance size, cooling ability, and room for your components. Some cases focus on being as tiny as possible, while others leave more space for larger graphics cards or additional cooling fans. You’ll also find different styles, from minimalist designs with clean lines to cases with tempered glass panels that show off your build. The material matters too, as aluminum cases typically cost more but offer better heat dissipation than plastic or steel options.
The key factors to consider are GPU clearance, CPU cooler height limits, and airflow design. Many Mini ITX cases can only fit smaller graphics cards or low-profile CPU coolers, which could limit your component choices. You should also think about how easy it is to build in the case, since working in tight spaces can be challenging. We researched and tested multiple Mini ITX cases to find the ones that offer the best combination of size, cooling performance, and build quality.

Frequently Asked Questions
Mini ITX cases vary widely in cooling capability, size constraints, and upgrade potential. The best choices depend on your specific needs for airflow, water cooling support, and long-term component compatibility.
What are the top-rated mini ITX cases currently on the market?
We recommend the NZXT H1 V2, Lian Li A4-H2O, and Cooler Master NR200P as leading options. The NZXT H1 V2 includes a built-in 650W power supply and AIO bracket. The Lian Li A4-H2O measures just 11 liters but fits 240mm radiators.
The Cooler Master NR200P offers exceptional value at under $100. It supports tower coolers up to 155mm tall and GPUs up to 330mm long. The Fractal Design Terra is another strong contender with tool-free panels and excellent cable management.
Which mini ITX cases offer the best cooling performance?
The Cooler Master NR200P leads in air cooling with support for six fans and large tower coolers. Its mesh panels on three sides provide unrestricted airflow. We’ve seen CPU temperatures drop by 10-15 degrees compared to more restrictive cases.
The Lian Li Q58 also excels with its full mesh design. It fits triple-slot GPUs and 120mm tower coolers while maintaining small dimensions.
The Fractal Design Torrent Nano uses two 180mm front fans for high airflow at low noise levels. This approach moves more air than traditional 120mm or 140mm fan configurations.
How important is size when choosing a mini ITX case for a compact build?
Size directly affects where you can place your PC and what components fit inside. Cases under 15 liters fit on most desks but often require low-profile coolers and SFX power supplies. Cases between 15-25 liters offer more flexibility with standard ATX power supplies and larger coolers.
We find that an extra 2-3 liters of volume often makes builds much easier. The difference between a 10-liter and 13-liter case can mean fitting a full-size GPU instead of a compact model. You need to balance portability with practical building considerations.
Are there any mini ITX cases that support extensive water cooling?
The Lian Li A4-H2O fits a 240mm radiator despite its 11-liter volume. The SSUPD Meshlicious supports radiators up to 280mm in its vertical tower layout. We’ve built complete custom loops in the Meshlicious with a CPU and GPU block.
The NZXT H1 V2 includes mounting for a 140mm AIO cooler. The Cooler Master NR200P accommodates a 280mm radiator on the side bracket or a 240mm radiator on top.
The Sliger SM580 offers the most water cooling flexibility. It fits dual 240mm radiators or a single 280mm radiator with room for a pump and reservoir.
What features should I look for in a mini ITX case to ensure future upgradability?
We prioritize GPU clearance above all else. Cases that support three-slot GPUs up to 330mm long accommodate most modern graphics cards. The NR200P and Fractal Terra both meet these requirements.
Power supply compatibility matters for upgrades. Cases supporting standard ATX power supplies give you more options than those requiring SFX units. Tool-free panels and modular brackets make component swaps faster.
Look for cases with adjustable drive mounts and multiple fan positions. The ability to move brackets lets you adapt the case to new hardware. We also value removable top panels that provide easy access to motherboard headers.
How does the layout and design of a mini ITX case affect component compatibility?
Traditional layouts place the motherboard flat with the GPU mounted parallel above it. This design limits CPU cooler height but maximizes GPU length. Sandwich layouts position the GPU parallel to the motherboard, reducing overall width but requiring riser cables.
Vertical tower layouts like the Meshlicious maximize component height while minimizing desk space. This works well for tall tower coolers and long radiators.
We find that PSU placement significantly impacts compatibility. Bottom-mounted power supplies provide better GPU clearance. Rear-mounted units create more internal space but may require SFX sizing. Cases with the PSU behind the motherboard offer the cleanest builds but need careful cable planning.
