The Carbide Series Air 240 by Corsair is a highly practical small form factor PC case. The unit allows the use of two 240mm radiators with a mini-ITX motherboard or a single 240mm radiator with a MicroATX dual-GPU setup. That alone shows much you can throw inside this case. Just becasue you're opting for a smaller case, it doesn't mean you need to sacrifice cooling performance. It's not too pricey either, coming in at $84.99.

Bottom line: The best all-rounder when it comes to small PC cases that can support MicroATX boards and even water-cooling loops.

One more thing: Support for full-length GPUs.

Why the Corsair Carbide Series Air 240 is the best mini-ITX PC case

This small case from Corsair is called the "Air" for a very good reason. It allows for high levels of air to be pushed through the chassis, thanks to three included 120mm fans, and support for up to two 240mm radiators with a mini-ITX board, or a single 240mm radiator with MicroATX setup. And yes, this case supports MicroATX motherboard sizes, which makes for quite the capable gaming rig.

A gaming rig (or capable HTPC) wouldn't be anything without a powerful GPU and the Air 240 can support full-length GPUs. Have a new GTX 1080 at hand? Throw it into the PC and enjoy the end result. The window on the side makes it possible to install some LED lighting to showcase expensive internals and can make for a great-looking companion at LAN events.

All this makes for a solid small PC case we feel is the best you can buy today for your next build. Not only can you pick up the case on its own, but Corsair has two other options available — one with a fan and another with a PSU.

This box is ideal as an HTPC or even a compact gaming build. The best part is, of course, the price at $39.99.

Sporting curved steel panels, massive amounts of cable management space, support up to three radiators, as well as the ability to mount two reservoirs, this is a killer case for PC builders who enjoy customizing the case. The only drawback is the price, which at $129.99 is a little high for a mini-ITX case.

One more thing: Modders have been able to modify the case to fit MiniATX motherboards.

Best Compact

When you really are restricted on space, you will struggle to best the Silverstone Milo ML05. Coming in at only 7 liters, this is an incredibly compact case. And because of this, you'll only be able to fit in two 80mm fans, an SFX power supply, and mini-ITX motherboard. While four HDDs or SSDs can be installed, this case is mainly designed for a NAS setup or lightweight HTPC.

At $51.28, it's a great option for those looking to carry out their first home network optimized build.

Bottom line: Super compact case that allows for placement in even the most restricted spaces.

One more thing: You'll only be able to use SFX power supplies in this case.

Best Mid-range

Phanteks is renown for the company's excellent range of PC cases. Whether you're gunning for a full tower or a small compact offering, you really can't go wrong. The Enthoo Evolv takes the usual cube shape that many mini-ITX cases share and adds a little design magic to transform it into an aggressive-looking beast. Not only do you have a contrasting color scheme, but also a stylized front panel with openings for fans to draw in cool air.

And there's ample scope for cooling with this case, allowing for up to five 120mm units to be installed — not to mention water-cooling support. HDDs and SSDs can be installed in a number of locations, and the Hoop-N-Loop cable ties help keep the mess under control. All this for $69.99 makes it a steal of a deal.

Bottom line: A highly stylish design meets solid cooling and an expansive chassis.

One more thing: Go all out with water-cooling with this compact case.

Best Portable

There are times when you need to carry your PC and some case designs make it difficult or uncomfortable to do so. This is where BitFenix decided the company would offer the Prodigy to address this issue. If you need a ITX case for LAN events or to take along on a journey, then this is a solid option thanks to two integrated handles. As an added bonus, five 120mm fan mounts make sure components housed within remain cool. Not bad for $84.99.

Bottom line: A great compact cases with two handles for easy transport to LANs or around the house.

One more thing: Thanks to not being too compact, the Prodigy supports a full ATX PSU.

Best Design

Thermaltake Core P1

Much like the Core P3 and P5, the P1 is all about being open and showcasing exactly what is powering everything. If you're looking for a smaller case but still want to show off all your shiny new PC components, this is definitely the case for you. There is loads of space to work with and is an incredibly sturdy case, sharing the same design as other Core P cases.

At $92.60, this is by no means an affordable case, but throw in some LED-sporting components and you now have an incredible sigh to behold.

Bottom line: A gorgeous case that ignores unnecessary external panels to show off what's installed.

One more thing: Comes with Thermaltake's cheap and unreliable PCIe extension cable for the GPU mount tray.
