The mini-ITX market has exploded in the last few years. People want power in a compact form factor. They want more usable desktop and floor space. With the right components, you no longer need a big PC to handle some hardcore modern gaming. 

If you’re looking to build a new compact PC there are a heap of great options but we've gone ahead and picked out the ones we loved working with. They're fun, compact, and usually look great when completed. If you want a build that's easy to move and can still kick ass, a mini-ITX rig might be for you.

That said, mini-ITX cases are often much tighter in terms of clearances and room for error. You'll have to spend more time planning your build, and making sure you buy components that will actually fit inside the case. (Several mini-ITX cases can't handle full-size video cards and power supplies)

It’s worth noting that cable management is key to any mini-ITX build. Mini-ITX cases don't offer a lot of place to stash your wiring mess, so make sure to cut down on cabling as much as you can. If you can use an M.2 SSD (even a SATA-mode M.2), go for it. When choosing a PSU, go for semi- or fully-modular so you can keep the excess out of the case. While these two considerations can keep any rig looking clean, they become even more important when physical space is at a premium.

On a technical note, all case manufacturers define a mini-ITX case as having a maximum of 2 rear slots. All of our choices fit this requirement. With all of that said, here are our picks for this amazingly fun form-factor.

Best high-end mini-ITX PC Case

  • Inverted motherboard layout
  • Easy installation and cable management
  • Compatible with large graphics cards
  • "Front" USB located on right side panel
  • Requires SFX power supply
  • Only supports 120mm liquid cooling

The BitFenix Prodigy quickly became one of the best selling ITX cases due to its unique design. Now it looks like the company is once again gunning for the throne with the instantly recognizable Portal Mini-ITX case.

Drawing obvious design inspiration from Valve’s Portal series, BitFenix’s latest ITX case features a distinct style that looks great as an HTPC in the living room or a gaming PC on a desktop. Measuring 9.7” x 15.6” x 16.2” with the stand installed, the Portal is quite compact and fits just about anywhere. Of course, this brings a couple of major flaws, like the requirement for a SFX power supply and lack of support for larger radiators.

Best mid-range Mini-ITX PC case

  • Good air flow that is directed to GPU and mobo
  • Lots of mounting options for 2.5-inch drives
  • Classy aluminum construction
  • Really tight for installing radiators

If you're looking for an affordable mini-ITX case that looks great and can accommodate a reference-blower graphics card, this case is well worth our attention.

The Enthoo Evolv iTX is great on a number of levels. It's moderately priced, and offers water cooling options and space for a full-length GPU in a form factor that has a much smaller footprint than an ATX tower.

Best budget Mini-ITX PC case

  • Cheap, cheap, cheap
  • Tiny little cube you can put anywhere
  • Space for two 2.5-inch drives and one 3.5-inch drive
  • Takes an ATX PSU, which is big for this size
  • Cramped quarters for cabling
  • Air flow can easily be restricted by PSU cables
  • No room for water cooling or big aftermarket air coolers

When you boil it down to basics, this case is about as basic as you can get. While feature reduction has it's ups and downs, this case minimizes the negative and offers one of the smallest form factors we've seen.

The Cooler Master Elite 110 is a very inexpensive case that manages to pack all the basics into a tiny form factor. At under a cubic foot in size volume, this little guy is about as small as you can get while still using an ATX power supply.

Best living room Mini-ITX PC case

  • Slim design works everywhere
  • Excellent water cooling support
  • Vertical or horizontal orientation
  • Full-size GPU support
  • Requires SFX power supply
  • Only supports one 3.5" drive

When it comes to PC cases, it’s incredible to see how far we’ve come along from the boring old beige boxes of the early 90s. Gamers and enthusiasts are now proud to display their systems on their desks. And while there have been a few options that are great for the living room as well, Phanteks topples the competition with the new Evolv Shift and its larger brother the Evolv Shift X.

With its brushed aluminum front, dual tempered glass panels and slim design, the Evolv Shift is easily one of the most elegant cases we’ve seen to date. It sits beautifully on any desktop and can even be placed horizontally to fit various configurations in the living room.

Honorable mention

  • Carrying handle
  • Supports full-size GPUs (up to 11 inches)
  • Room for two 3.5-inch drives
  • Door design is easy to open and close
  • Cable management is about average

This little case from Corsair offers a portable package and that fits full-size GPUs. We like it, and we've used it as a base for a few systems. The case offers everything you need, including a nice little carrying handle.

The Corsair Graphite 380T is loved by many for its features and size. With room for 11 inches of GPU and water cooling for the CPU, this case does have a lot to offer.

Judge me by my size, do you?

When it comes to building PCs, the mini-ITX form factor is where we've seen the vast majority of innovation in design. The small form factor allows for a number of forms for the PC to take, since cases aren't slaved to the long rectangular prism needed to accommodate a full-size ATX board.

While a mini-ITX build takes a little more patience and experience to do well, the rewards are much higher. Having a small, clan build in an interestingly compact package makes you feel good. Mini-ITX rigs make it easier to take your rig to a BYOC LAN party, or play PC games in the living room (if that's your thing).

Big PC power really can come in small packages.
