The MITX mini ITX case is the perfect size for your next build. The cases are budget-friendly but still come with features that make them worth it.

Before purchasing a case for your Mini-ITX gaming PC, consider several things.

First and foremost, be mindful of the dimensions of your components (form factor). Because the form factor of motherboards, GPUs, and power supplies might vary, it’s critical to double-check compatibility! Also, before starting a build, think about how many fans you’ll need, how many hard drives you’ll need, and what size radiator your cooler has!

Don’t worry. We’ll go through each of these aspects in more depth further down.

Dimensions of the Motherboard


You only need to worry about purchasing an mITX board if you search for the most acceptable Mini-ITX PC enclosure. However, most Mini-ITX cases, if not all, are incompatible with bigger mATX or ATX motherboards, so make sure you pick the proper one!

Smaller boards will offer less space for your components and, as a result, fewer functionalities. This isn’t a terrible thing if you don’t need much, but if you’re building a high-end gaming system or even a mid-range system that you want to enhance in the future, you should select traditional ATX boards with a mid-tower.

Your Case


The motherboard compatibility is usually included in the case’s name or the specifications, and it specifies a giant motherboard that can fit inside the case. As you can see from this list, all cases are designated as mini-ITX,’ indicating that you’ll require components with comparable form factors.

There are three main kinds of computer cases (although there are more), each of which is compatible with various motherboards:

  • Full-tower cases are the biggest and support E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards. Their colossal size is aimed toward high-end gaming PCs with additional components rather than motherboards that are unusually large.
  • Mid-tower cases are the most common, and they can accommodate motherboards up to ATX size.
  • The more giant ATX boards are sacrificed in Mini-ITX cases, and although some can still accept Micro-ATX, Mini-ITX boards are their primary emphasis.


It’s worth mentioning that your mini-ITX setup will only look well in a small to mid-sized tower due to the cable length frequently having trouble reaching a mini-ITX board from a more significant case. Although some patients may have taken this into account, you may find it challenging to keep your build looking as clean as possible when cable management on your front panel since they may be stretched.

Frequently Asked Questions

What is the best Mini-ITX case?

A: The best case is the Fractal Design Mini-ITX R3. It’s explicitly designed for HTPCs, and it offers a lot of flexibility in terms of its design.

Are Mini-ITX builds worth it?

A: That depends on your budget and what you are looking for. An ITX build is excellent if you want to keep a lean, clean look, but the lack of space may become an issue depending on the components that come into play.

Why are Mini-ITX cases so expensive?

A: There are a lot of parts inside the case, and it is tough to produce. It would be best to have metal or plastic molds, custom circuit boards, and high-end cooling solutions for this form factor.
