The 5 Smallest ITX Cases of 2024 (Best Mini ITX Case Options)

Smallest mini-ITX cases

The 5 Smallest ITX Cases of 2024 (Best Mini ITX Case Options)

Key Points

  • PC builds are becoming smaller and more efficient, with mini-ITX cases reducing volume, footprint, and weight for easy portability.
  • When choosing a the best small pc case like a mini ITX, consider factors such as build space, cooling capacity, options, and price. These are the smallest pc cases out there, so using one requires careful planning and consideration of component sizes and cable management.
  • Mini-ITX cases offer the advantage of portability and customization without sacrificing performance or features.

PC builds just keep getting smaller. From easily assembled PC build kits to the smallest ATX cases to reduce the footprint of personal computers, technology increases efficiency and reduces size. Now, the smallest mini-ITX cases take PCs to an even smaller scale, reducing volume, footprint, and weight to become easily portable and hardly noticeable. 

Mini-ITX cases get their name from their design: they house a mini-ITX motherboard. This 6.7 by 6.7-inch form factor is not exactly new, but its popularity is certainly increasing among builders. Although not large enough to house a full-sized ATX or larger motherboard, they are still capable of basing a powerful gaming PC, business computer, or another useful device. Storage capacities are larger with smaller frames, process nodes are smaller than ever, and most PC builders just don’t need a large tower anymore for a dedicated system. You can tailor your build to your purpose, including case size. 

Builders must tune their system to the smaller mini-ITX cases with compact graphics cards and small-form-factor (SFF) power supplies, but this does not mean trading performance for convenience. In fact, the mini-ITX cases we showcase here support full-length graphics cards and other components. Still, double-check sizes and clearances with every component and your chosen mini-ITX case. So let’s dive right into our selections for the five smallest mini-ITX cases. We know you’ll be ready to rush out and order yours when we’re finished!

How to Pick the Smallest Mini-ITX Cases: Step by Step

If you enjoy completing intricate and challenging puzzles, then choosing and building PCs in the smallest mini-ITX cases is for you. It’s all about balance — between size, available volume, and case configuration — that allows you to build the computer you want in such a compact unit. Achieving that balance requires advanced planning and research to discover the best possible combination to achieve your goals. 

Of course, this largely depends on how you plan to use your compact PC. Are you traveling to LAN parties with your own portable system? Do you need a compact business computer for travel? Does a small PC at the side of your desk meet your needs? Measure what you must have to get the job done and work backward to find the smallest mini-ITX case that will support everything you need. 

When choosing the best smallest mini-ITX cases, there are four main considerations for most PC builders. 

  • Build Space (size, volume, case configuration) 
  • Cooling Capacity 
  • Power Options
  • Price

Let’s review each of these criteria in more detail.

Build Space

What we’re calling “build space” is the available area within a mini-ITX case to contain all your components and cabling. Three considerations are paramount here: size, volume, and case configuration. Each one affects the others in a choreographed dance of tradeoffs that can be maddening. 

Size is the first factor because you already know you want to build small. Big towers and even smaller ATX cases are out. You want something within the mini-ITX form factor and that means a mini-ITX motherboard supporting full-size components. The average size will be around a foot square or less, depending on the form factor design (vertical, cube, etc.). 

Volume is how much area there is inside the case to hold everything you need. Most components are measured in millimeters (120mm fan, 140mm radiator, 375mm GPU, etc.) so pay particular care to component measurements vs. the maximum lengths and widths your case will support. Don’t forget the cables! Moreover, you want sufficient space between components and the case panels for adequate airflow. 

Case configuration refers to how the mini-ITX case is built. The frame and its interchangeability or any removable or expandable features are big advantages. Prerouted cabling and cooling radiator tubes built into the case are also huge benefits. The more flexibility the case design offers, the better you can configure your build to contain everything you want. 

Cooling Capacity 

Small, compact mini-ITX cases shoehorn everything into the smallest available space, and that means potential cooling problems. Components lodged against the case or against one another are sure prescriptions for overheating and system failure. Balancing your desired component sizes with the smallest possible case is a juggling game. You want a few millimeters of breathing space around everything so airflow is not restricted. 

You also want a case that supports adequate cooling components for the system you build. Some of the smallest mini-ITX cases only support cooling fans, so your build must keep a lower temperature limit in mind. Those with radiator support and fans offer the best cooling capacity, but that takes additional space. Again, how you configure the case will determine if a radiator takes up space you need for memory or a larger GPU. 

Power Options 

In many of the smallest mini-ITX cases, you will sacrifice an internal PSU for space. Our tiniest selection requires a  DC-ATX power module and an external AC adapter to save space. More moderately sized ITX cases can offer an ATX or SFX PSU form factor option. The balance between compact size and your specific build purpose again comes into play. 

Many modern SFX PSUs provide enough power for high-end gaming, content creation, and more in their smaller size. Calculate your necessary power needs and a safety buffer when choosing which PSU will power your mini-ITX PC build. 

Price

Virtually anything is bought for the right price. Our choices range from the budget model for less than $100 to some climbing into several hundred dollars. Size, convenience, portability, and other factors impact price. One of our selections is great for newbie PC builders because it already contains some high-end parts preinstalled — but you pay extra for that privilege. Another of our choices requires a price upgrade to get a high-end PCIe cable for connecting newer components. As always, balance price with features and shop for the best deals available at the time you plan to buy.  

What to Know Before Buying the Smallest Mini-ITX Cases

With real estate buys, it’s location, location, location. Before buying the smallest mini-ITX cases, it’s all about space, space, space! Tiny ITX cases are popular because they are small, but you must know where to sacrifice. A larger case offers more build options. A smaller case offers more convenience. If you want convenience, prepare to think small and tight. 

Building a mini-ITX PC is more challenging. Every component and cable matters. The case configuration matters. The small space complicates even the simplest upgrades. Preplanning for what you want to build, as well as what you may want to do in the future, is essential. Experienced carpenters “Measure twice and cut once,” so experienced PC builders using the smallest mini-ITX cases plan and plan. You may need to calculate dozens of possible combinations before finding the ideal one for you. 

We recommend pre-building before connecting everything. Imagine finishing the 10th step only to discover step 11 is impossible in the available space. This includes routing all the cables and finding the best channels for them as you pre-fit components into place. Replace the panels and see how much space is between cables, parts, and the case sides. Sketch a diagram of your best assembly configuration before removing everything and building in earnest. 

Using the Smallest Mini-ITX Cases: What It’s Like

Building a computer using the smallest mini-ITX cases has several advantages. Imagine carting your huge PC tower to a LAN party! Plus, modern advances in mini-ITX technology mean you don’t sacrifice performance or features for size. You can create a fully customized gaming PC, traveling LAN party rig, office computer, or portable content-creating station for a low cost.
