  • Very easy to build in
  • Affordable
  • Does not fit all hardware

Small form factor builds are notoriously difficult. Squeezing your hands into the tight spaces inside these tiny cases can be challenging, especially when one hand is trying to hold a part in place, the other is trying the screw it in, and your elbow is keeping cables from getting caught up in the mix.

The task of cramming everything into the space you’re given can be overwhelming for a lot of first time builders, and even some veterans. However, a case like the Thermaltake Core V1 can help remedy this. This case uses a clever design that allows for all of the side panels and the front to be removed. This leaves you with just the basic frame of the case and gives you more room and angles from which to work.

The case also has a nice compartmentalized design that allows you to put the power supply underneath the motherboard and other hardware, which makes cable management much easier. The case has a transparent window, and thanks to the interchangeable side panels this can be placed on the top or either side.

Both of the other side panels on the case, as well as the front, are made from a breathable mesh that offer pretty solid cooling performance. What’s even more impressive is that the case can fit a monstrous 200mm fan in the front for maximum airflow.

How to pick the best mini-ITX case for your needs

The charm of a mini-ITX case lies in its ability to house a full-powered PC in a significantly smaller footprint compared to traditional mid or full-tower cases. This makes them ideal for setups with limited space or for those who prefer a minimalist aesthetic without compromising on performance. However, choosing the right mini-ITX case involves careful consideration of cooling solutions, component compatibility, and design preferences. These cases must balance size constraints with adequate airflow, support for high-end hardware, and flexibility for future upgrades.

While we always say it’s nearly impossible to pick the best of a given item because defining what’s the best is up to you and your needs, this tired trope is particularly true when it comes to finding the best ITX case. This is thanks to things like cooling and compatibility, which can have much more of an impact thanks to the extra small scale.

To help you make sure you’re getting the right case for your needs, we’re going to look at three major factors to consider when in the market for a new mITX case.

Size and compatibility

It seems obvious that size would be a consideration when choosing a case for a small form factor build, but there are several things to look at when it comes to size. Not only do you want to look at the overall dimensions of the case to ensure it will be the size you want, but the graphics card and CPU cooler clearance should also be taken into consideration.

Many people will choose a shorter cooler or even water cooling by default when planning a small form factor PC, but if you want to get the most out of your hardware, a bigger cooler is always better. Some of the largest coolers on the market get up to– or even over– 160 mm in height.


Cooling is arguably more important in small cases than in mid-towers since the air in the case can heat up much more quickly and to much higher temperatures since there is a much smaller volume within the case. If you’re going to use high end or notoriously hot running hardware, then make sure your case can fit plenty of fans, has good airflow, and even consider water cooling.


If you have a large library of games, movies, or music, then you know the feeling of running out of space and having to uninstall or delete things to free up space. The best way around this is to simply add more drives to your system. However, in small form factor cases space is at a premium, so drive bays can be hard to come by.

Generally, there are two kinds of drivebays to look for. 3.5-inch bays are for standard hard drives which, while slower, usually offer terabytes of space at a good price. 2.5” bays, on the other hand, are for solid state drives, which are much faster and can drastically reduce loading times in games, but cost much more and offer less storage.

Can you game on a Mini-ITX PC?

Absolutely! Not only is a mini-ITX PC suitable for gaming, but in some scenarios, it can offer an enhanced gaming experience. Their compact size doesn’t hinder their ability to house powerful components, making them capable of running most modern games efficiently. The key is to select components that fit well within the constraints of a smaller case while still meeting your gaming needs.

Our Verdict

The Lian Li Q58 tops our best mini-ITX cases list. It shines as a top pick for its excellent balance of form and function, offering a sleek design without compromising on component accommodation or airflow. Its versatility and high-quality build make it a prime choice for anyone looking to construct a powerful yet compact system.

For those prioritizing durability and build quality, the Streacom DA2 V2 stands out, while the Fractal Design Terra offers a unique aesthetic departure from the typical gaming look. The Corsair 2000D RGB Airflow, designed for enthusiasts, packs a punch in cooling efficiency and aesthetic appeal, despite its small size.
