If my computer fan roars, it drives me insane. I also like to game in my dorm, where I don’t necessarily have a ton of space. That’s why an ITX case was a perfect choice for me, and why I keep using them. Because of the basically micro ITX cases I own, I’m able to put gaming systems in any room, which gives me tons of flexibility. Unlike the best NAS case, which aims for more storage and security, when you’re buying a good ITX PC case, you’re investing in a system that not only adds flair to your space, but protects your hardware. I’ve broken down what I look for in a great ITX case so you don’t have to make the same mistakes that I did.

What to Expect From an ITX Case
A great ITX case will optimize your gaming experience by providing you with the ability to load it up with the latest technology. They should be roomy, have ample IO additions, not overheat, and be portable. On top of being well-ventilated, they also need to be incredibly sturdy and should run cool and quiet. You can hope for the same features in affordable cases we also reviewed.

A truly stylish setup created by lighting for a system that elevates your gaming space
A strong fan that keeps your system from overheating for longer gameplay
A prebuilt PSU with cables that are already managed so you don’t have to configure or rearrange them
Powerful A1 Qi charging station so your tools are always ready when you need them.
This rig is awesome. It can be personalized with a fantastic lighting effect and comes with two complimentary Sirius loop ASL120 fans. The structure itself is matte black and has dual redressable RGB loops. Because of the placement of these loops, lighting is present no matter how you choose to set up the fan.
The InWin A1 also comes with a wireless charging station, which is very convenient and is now WPC Qi. 1 certified, as well. This bad boy emits 10W of power, which is enough to cover the tower as well as the mouse I use. In my opinion, this is the best ITX Case because it’s convenient and powerful, as well as really interesting to look at. It adds a technological flair to any setup.

In my experience, the power supply has always performed well, and because the ITX case is so compact, I was able to fit my entire setup in a pretty small dorm room. This was a major plus for me, and would also be very valuable for anyone who values portable ITX cases.
If you really want to showcase the inner workings of your PC case, this would be a great aesthetically pleasing ITX for you. It adds a clean but interesting look to any space.
Because of its rounded off square shape, installation is easy. The space to install powerful hardware is also there, which is crucial. There’s also space to support a CPU heatsink smaller than 160mm, and can take graphics cards up to 320mm in length as well. The front IO is also very complete for a small ITX case. These ITX cases can do it all, and are powerful and keep cool while doing it.

If you have standard length expansion cords, you’ll be incredibly happy with this purchase. This, more than other mini ITX cases, fits more standard sizes across the board. The build also fits a single fan with all-in-one liquid cooler, and due to the mesh tops and sides, doesn’t overheat without the extra power.
This build does its job well, and has a classic sleekness to it while simultaneously remaining cool and functional. It’s compatible with mini ITX motherboards as well as ATX PSU, and supports 2 5” and 3 5” hard drives, meaning you can pack a lot into this little case. This is a sturdy, reliable build case that allows you to pack in more than anticipated.
It is the reliability alone that makes this particular build worth every penny. The ventilators aren’t extraneous, and it isn’t loud in your space, even when it runs for extended periods of time. Overall, I’d say that this case runs cool and quiet, which is everything you could ask for from a mini ITX.
Cooling is a major source of woe for any gamer. If your systems get too hot, you’re done for. So when you’re working with an ITX build, the cooling system is incredibly important. Due to their small size, it can be hard to make a selection in which the fan is amply powerful, or there’s a truly worthwhile liquid cooling system.
Overheating slows down your machine by causing problems within the hardware itself. If you don’t take care of your cooling system, you won’t have a build, especially if you use a portable build. High-quality fans need to be present in any type of ITX build that may move around a lot, especially if you want to have quick gaming speeds and intense graphics.
The power in your machine comes from its core. By choosing one with high frequencies and fully functional memory slots, you’re likely on your way to having a useful core. Tons of differences arise at this stage, and they can really affect price. What you’re looking for are cores that can create high-quality graphics and potentially multiple expansion slots.
Your core should be able to handle a large amount of GPU, and shouldn’t overheat easily. Dedicating your time to figuring out what level of core performance you need for your own gaming systems and goals will work out financially in the long run by preventing you from under-investing in your core.
The GPU is the graphics card, and the size of the GPU in some cases determines the quality of your graphics. If the card is too large, then you won’t have space within your ITX for efficient memory or cooling systems. However, if you don’t have a proper graphics card, then you lose a lot of the quality of the gameplay. It also determines the dedicated memory of your card. If your GPU is optimized, you will have a more enjoyable experience, especially if you use your build for competitive gaming.
Keep in mind that your riser cable needs to be close in quality to your GPU, because they tend to work in conjunction. Going all-in for a GPU but neglecting the riser cable may still leave you unsatisfied.
Riser cables can mount and display or graphics cards, and are used for GPU solutions in order to enhance the quality of your game. A quality riser cable is easy to install, has minimal signal loss, and has precise contacts for securing it into your case. Slim designs are typically preferred, as are designs that can be vertically placed in order to really take advantage of the space within the build.
Case airflow prevents overheating. It’s vital that enough air moves past your working parts in order to move heat away from the radiator and other parts of your hardware that can become overheated and damaged.
Something to take into consideration is whether you’d like to have fabric mesh on your case. This increases airflow and encourages the dispersal of heat, but also can lead to alternate forms of damage in any sort of spill or accident that may otherwise have been prevented from a harder exterior.
Case fans need to be durable in order to increase the amount of airflow moving through the exterior of the machine. They assist with the cooling process, and ensure that your machine continues to function at top capacity.
Another consideration to take when choosing a fan system for your ITX case is how easy it is to reach the fan. Fans get dirty, as do the filters within the builds, so being able to have access to clean and correct will not only save you money, but improve the speed and quality of your build.
If you expect to transport your build, you need to make sure that you’re investing in a quality fan. When your build moves, the fan may shake and move with it, which can cause damage to the fan or even the other parts of the build. Any damage is going to cause slower gameplay, decreased graphics, or even potentially overheating. A happy cooling system is a happy mini-ITX case, and if you want the best performance from your ITX size mini ITX case, you need to care for your cooling system.
What You Want From a Mini-ITX Case
You want your Mini-ITX case to perform. That’s it, at the end of the day. I’ve had mini-ITX cases that have overheated, lost the quality of their graphics, not contain enough space for the type of build I needed, and even lack the necessary IO requirements for connecting and playing.
