The Carbide Air 540 is not quite compact, measuring 15.4 inches by 13.3 inches by 14.2 inches. This is due, in large part, to its dual-chamber architecture, which separates distinct components, the correct housing of which typically requires larger cases.

Despite its size, it nevertheless provides a form factor that is rather compact and does not compromise on either performance or features in exchange for its smaller stature.

In addition to white LED lighting that illuminates the power and reset buttons on the front panel, the front panel also includes two USB 3.0 ports, headphone/microphone jacks, and two more USB 2.0 ports.

The front panel has connections for headphones, microphones, and USB 3.0 ports. The power and reset buttons are located along the top edge and are backlit with white LED lights.

Although it is not quite compact by any stretch of the imagination due to its dimensions of 21.65 inches by 9.76 inches by 23.62 inches, this is still very lightweight at just over 27 pounds without having hard drives or components installed yet.

To give you an idea of how much room you have available, the case itself has nine expansion slots, and the top panel has three more slots that can be used for external drives or additional hardware. These expansion slots can be used interchangeably.

The fact that you desire a small and compact chassis for your Micro ATX build does not imply that it has to have a plain or uninteresting appearance because there are a lot of different options available right now, some of which have intriguing design choices.

Take, for instance, the Lian Li PC-Q32 as an illustration. It is one of the newest Micro ATX cases available right now and is manufactured by one of the oldest names in computer case manufacturing, so you can be sure that they know what they’re doing even at a more affordable price point like this one.

With a minimalist, all-black exterior, it has a distinctive appearance that makes it stand out from other cases on the market. However, it still manages to be less than 12 inches tall, making it ideal for saving space in tight entertainment centers or workstations. This is accomplished without sacrificing any of the features that are necessary for regular use.

This Micro ATX model has dimensions of approximately 9 by 11.8 by 7 inches, making it noticeably more compact than the vast majority of full towers on the market. However, it still provides sufficient space on the inside to accommodate your hardware, including high-end graphics cards and multiple storage drives at the same time.

There are also two preinstalled 120mm fans here with conventional mounting holes in addition to one exhaust fan for fantastic ventilation overall. In addition, there are lots of connectors around the back including USB 3.0 inputs for quickly transferring data between your computer and external devices.

Even though it measures just 14.6 x 8.3 x 16.1 inches, making it even smaller than the Cooler Master Masterbox Lite 5, which is designed for Mini ITX builds rather than Micro ATX, there’s still room inside to fit quite a few components, including one optical drive bay up top and another on the front panel in addition to three storage bays in total with cages built into the interior to keep everything organized neatly. The cages are built into the interior to keep everything organized neatly.

  • Extra-Thin design fits well in any setup
  • Roomy enough for most components
  • Slim, compact design
  • Not many extra features compared to larger designs

5. Thermaltake Core V1

If you want to create an ITX PC in the near future, it does not mean that you have to go out and spend a lot of money on a massive case that has a lot of features that you will never use, nor does it mean that you have to be able to put all of your components inside without any problems.

The Thermaltake Core V1 is able to do both of these things at the same time by providing one of the most competitive prices available for a Mini ITX case while also maintaining a beautiful and contemporary appearance with an open frame design that allows for an abundance of ventilation.

It only measures 11.8 by 7.2 by 12 inches, so it is about as small as you can get without opting for something even more fundamental. However, there are some full-size options available on the market, including a few from Thermaltake, which cost a little bit more but offer a larger footprint instead.

Having said that, the interior of this model is still very spacious and can accommodate a large number of components, such as an ATX power supply that is mounted on the bottom, up to three hard drives with a 3.5-inch bay, one solid-state drive with a 2.5-inch bay below those bays, and up to six expansion slots at once for possible future upgrades.

Thermaltake includes one 120mm fan with white trim to keep everything cool. Additionally, a few spare screws are included in case you decide to add additional fans at a later time. The front panel is fully meshed to allow for a massive amount of airflow even when there are no additional fans installed.

This model has a sleek black finish, accents made of brushed aluminum around the edges, and a large hexagonal vent located on the top, and despite the fact that it is quite inexpensive in comparison to the vast majority of Mini ITX cases, it still manages to look contemporary and fashionable at the same time.

Because it does not require an excessive amount of space and is not very difficult to move from one location to another, it is an excellent choice for both the personal computer in your living room and the rig in your bedroom that is located close to the television.

  • Fast performance
  • Plenty of room for big GPUs and cooling components
  • Solid construction with a sleek design
  • Not many extra features compared to larger designs


These are the 5 smallest ATX cases that have ever been produced. These mid-tower cases are ideal for your next build of an HTPC or media center computer and are great for gaming builds as well. Both in terms of their functionality and their appearance, they are outstanding.

These full-size towers all have a height of fewer than 22 inches, which is more than enough room to accommodate the majority of the components around them.

Keep in mind that the purpose you intend to serve should determine the type of case that is most suitable for you. It is important to think about where you will put your personal computer and how loud it will be, as these factors will determine the sorts of fans and design components that are optimal.

The fact that a Mini-ITX case can save space in comparison to a full ATX tower is the most crucial aspect of this trade-off, as it comes at the expense of some cooling performance and some capacity for customization.
