Best Smallest ATX Cases
In the last decade, people have been more interested in building small and compact rigs. Sure everyone likes a PC with tons of high-end hardware but not everyone has the space to accommodate all the components and this is where the Small ATX case comes into the picture. They allow people to build compact yet powerful rigs without having PC components scattered all over their desk space. A Small ATX case will nicely tuck away all of your PC components and take less space; that is why people who live in small apartments often invest in a small ATX case. Plus ATX PC cases allow people to build small rigs that are more portable so it is used by people who travel a lot.
Some small ATX cases are also designed to offer better airflow which helps in keeping the temperature of the PC low. They also protect the PC components against dust and insects. Not to mention, well-designed PC cases can serve eye-catching aesthetics. That is why most people are going for small ATX cases. However, before you invest in a small ATX case you must consider some of its cons and weigh your options carefully. Some small factor PC rigs can end up costing way more than tower ATX builds. Besides this, most small form factor rigs can’t support multiple graphics cards. If you have already considered all these ideas and have decided that you want to build a small rig with a small ATX case then you have come to the right place.
I understand that it can be hard to select a suitable small ATX case for your rig and since they are newer as compared to some other PC components; not a lot of reliable information is available on the internet about them. That is why I have reviewed some of the best smallest ATX cases and compiled this list to assist you in making a choice. Each of the ATX cases listed here possesses all the options, features, and functions available in Tower ATX cases but they don’t occupy as much space as them. So without further delay; let’s get into it.
Our Recommendations for Best Smallest ATX Cases
Fractal Design Meshify C
Building their reputation from their mid-priced, yet high-quality PC cases, Fractal Design also introduced their lightweight models at reduced prices later on. Some of the keys feature that Fractal Design’s PC cases usually have like the anodized aluminum front panel and the asphalt sound damping was dropped to reduce the prices. However, those cases still have the firm’s classic solid face design. Adding a glass panel wasn’t enough for Fractal Design, so they went on to meshify their Fractal Design Meshify C PC case. Now that the front panel is a mesh instead of a solid front panel which was used in previous designs that would reflect some of the noise produced by the components back into the case, so this case may be slightly more noisy.
The intake fans in the front don’t have to draw air through the thin slots located on the sides of the front panel, this means that Fractal Design Meshify C will probably be able to keep your components a little cooler. The automatic fan controllers usually turn down the fans on the systems that manage to keep the temperatures in check, so a good cooling to noise ratio may be achieved. Fractal Design Meshify C PC case’s front panel is not smooth and is angled in different directions instead. The company claims that this increases airflow, but more likely benefit is that ripples won’t show on it like they often do on a flat panel.
The front I/O ports are located at the top of the front panel that features two USB 3.0 ports, a microphone jack, a headphone jack, a reset button and a power button. There is a mesh panel on the top of the case just behind the front I/O ports which is fixed by magnetic strips. On the bottom of the case, there is a full-length bottom dust filter that slides in from the front and covers both the power supply inlet and an optional intake fan. On the back side of the Fractal Design Meshify C PC case we have a removable power supply flange, just above it are seven expansion slots that have screw-on covers, and above that is a slide-able fan mount. The removable power supply flange allows the builders to put the power supply in from the back of the case and the exhaust fan’s screw slots allow the builders to make enough room for single-fan radiators.
The 3.5″ removable drive cage limits the power supply mounting depth to 8.9″ with the cables. The front panel comes off and reveals a removable center panel with encapsulated foam dust filter and also reveals the mounting locations for 2 x 140mm or 3 x 120mm radiators and fans. There is a single 120mm fan included. The builder can remove the 5.4″ removable panel which will provide enough room so that the Fractal Design Meshify C can support a large radiator. So, you don’t need to worry about space, even though the case is a little compact for an ATX PC case, but the case has plenty of space. The dark tinted side glass panel does a great job to suppress the excessive brightness of the lighting inside the PC case and kind of also helps to conceal component color mis-match.
If you have seen the Raijintek Styx, then the Raijintek Thetis will just look like a larger version which allows support for an ATX motherboard in a compact form factor. The Raijintek Thetis comes in either black or silver. RIght of the bat, you can tell that the internals of the Raijintek Thetis PC case are flipped upside down, since the windowed side panel is on the right side of the case instead of the left side which is the traditional design.

Several mounting points for a hard drive are also located here. Removing the side panels of the Raijintek Thetis PC case reveals the interior of the case which looks quite simple and lacks individual mounting plates or drive bays. In order to enable storage expansion and cable management, Raijintek is using the space on the motherboard tray. With about 20mm space behind the motherboard tray, it is enough to install 2.5″ drives and allow the builders for basic cable routing for a cleaner look. This side of the motherboard tray has two mounting positions for such drives. The bottom of the Raijintek Thetis PC case supports an additional 120mm fan. You can choose to install a 3.5″ hard drive here instead.

Corsair iCue 220T
The Corsair iCue 220T is an intriguing re-imagining of what is probably the most important piece of case design which is good airflow. Having a very outlandish design, Corsair iCue 220T introduces a new style for the front panel, going for a characteristic which usually does not favor perforated metal or solid panels. The front panel of the Corsair iCue 220T PC case has parallelogram cutouts that make the pressed-steel front panel more beautiful and provides a unique look. These also as ventilation holes which provides the fans in the front with a good amount of air.
Even though the case has three RGB 120mm fans, still Corsair has put the iCue 220T PC case as a budget PC case. It is a bold move by Corsair, especially with the case having such a unique style, tempered glass side panel and the included fans. The front panel is held into place with four individual metal pins at each of the corners, securing into latches on the front of the chassis. The sizable protruding cutout at either edge of the panel itself provides a 4cm gap between the front perforated steel plate and the front intake fans. There are three Corsair iCUE SP120 RGB Pro fans that the case comes with, they are plugged in an integrated RGB controller that does not control the fan speed and only controls the lighting.
Having a different internal design than most of the Corsair’s other PC cases, the Corsair iCue 220T PC case stands out. This PC case has a full-length power supply shroud. It also has cable pass-throughs for the GPU cut out of it and many rubber grommets in place everywhere else that keeps all of the cables out of the way and tidy. On the back of the motherboard tray, you will find a two-slot 3.5″ hard drive caddy in front of the mounting location for the power supply and two 2.5″ SSDs mount on the back of the motherboard tray.

The front of the Corsair iCue 220T PC case supports either 2 x 140mm or 3 x 120mm fans, 2 x 140mm or 120mm fans at the top of the case and a single 120mm fan in the rear. You should not face any problems if you want to mount a 240mm AIO at the top of the Corsair iCue 220T PC case since the top fan mounting positions are offset from the motherboard tray. Even though the Corsair iCue 220T PC case is a little bit on the smaller side for a mid-tower ATX PC case and internal space is a little bit compact than most. But, Corsair iCue 220T PC case supports up to full-ATX form factor and GPUs up to 300mm. You will probably not be able to put much else in the case in terms of bulky hardware.
