The 5 Smallest Mini ITX Cases for Compact and Portable Builds

Mini ITX cases continue to shrink in size while packing a powerful punch. As components get smaller and more efficient, builders can cram high-end parts into tiny spaces for ultimate portability and convenience. Choosing the best small case for your needs means balancing size, available build space, cooling capacity, power options, and price.

I‘ve assembled this expert guide on the top 5 smallest mini ITX cases to consider for your next compact PC build. Whether you need a LAN party computer, portable workstation, or just a tiny footprint on your desk, one of these mini ITX cases will get the job done. Let‘s dive in!

What to Consider When Buying a Mini ITX Case

Building a computer in a mini ITX case requires more planning and precision than a standard ATX build. You‘ll be working in tight quarters, so proper component selection and clever cable management are musts. Here are the key factors I evaluated when picking the best smallest mini ITX cases:

Size: The overall dimensions (height, width, depth) of the case. Smaller isn‘t always better if it restricts component support.

Build Space: The interior volume and layout that determines what parts you can install. More compact cases have less wiggle room.

Cooling: The number of fans, radiator mounts, and ventilation to prevent overheating. Cooling is tougher in small spaces.

Power Supply: Whether the case natively supports standard ATX power supplies or smaller SFX form factors.

Expansion: Drive bays and slots for storage, graphics cards, and other add-in parts. Mini ITX cases offer less upgradeability.

Price: Cases can range from budget models under $100 to premium designs over $300. Set realistic cost expectations.

I evaluated dozens of mini ITX cases and narrowed the field to the smallest and most capable options. All support full-size, dual-slot graphics cards with some disassembly. Some even handle triple-slot cards!

Let‘s look at the top 5 smallest mini ITX case picks in more detail.
