Best Micro ATX Cases

Today, we’re going to review ten of the best Micro ATX cases on the market, and we’ll provide you with all of the relevant specs before getting into a more general overview of each product.

We’ve gone over a vast range of cases so that everyone can find the best Micro ATX case for their requirements.

Best Micro ATX Case


NZXT H200i

  • Available in a range of color combinations
  • Features integrated lighting and an RGB fan controller
  • Adaptive noise reduction balances fan noise and cooling
  • Comes with three 120 mm fans

If you’re willing to spend a little more money on your computer case, then the NZXT H200i is the best Micro ATX case in our opinion. This model is available in four different colors, and it comes installed with RGB strips that will allow you to customize it to your heart’s content.

The included RGB fan controller makes it easy to adjust the cooling on this case. One of the best things about this case is that it was designed with cable management in mind, so you’ll have plenty of slots, channels, and velcro straps that you can use to keep them in order.

Since this computer case features adaptive noise reduction, you can run your fans at higher RPMs without worrying about excessive noise.

Best Value Micro ATX Case


AeroCool Cylon

  • Features an acrylic side window
  • Front panel LED with 13 lighting modes
  • Equipped with a removable dust filter
  • Comes with a pre-installed case fan on the front

AeroCool’s Cyclon case is one of the better-looking options on our list, and it’s also more affordable than many of the other products available. The LED slash that runs through the front panel features 6 RGB flow modes and 7 solid colors, giving you 13 potential looks.

Unlike many other budget cases, this one also has a USB 3.0 port on the top I/O, and it also supports SD and microSD cards. There is a dust filter installed over the CPU fan ventilation port that can be removed for cleaning without having to take apart too much of the computer, improving convenience.

Best Budget Micro ATX Case


Cooler Master MasterBox Q300L

  • Acrylic side panel improves visibility
  • Comes with dust filters
  • Cable management space behind the motherboard tray
  • Vertical or horizontal orientation

The second entry on our best Bicro ATX list from Cooler Master is the MasterBox Q300L, which provides you with nearly as much value for money as the MasterBox Lite 3.0.  This case comes included with a transparent acrylic side panel that will allow you to show off your cable management skills and components.

The most impressive thing about this case is the way that the magnetic dust filters are designed, as they play both a practical and aesthetic role. These removable magnetic filters feature a geometric design that will keep your case looking good, and since they’re externally mounted, you can clean them easily.

There is also room behind the motherboard tray so that you can keep the cables out of sight, which is an essential feature for a windowed PC.

Best Cube Micro ATX Case


Thermaltake Core V21

  • The motherboard can be oriented vertically or horizontally
  • Comes with a 200 mm front fan
  • Dual chamber design for optimal cooling
  • Can support a total of six storage drives

Another excellent case is the Thermaltake Core V21 which is perfect for both mATX and Mini-ITX builds. In addition, its stackable design means that you can even create dual systems with two of them. One of our favorite things about this case is that it has a dual-chamber layout which greatly enhances airflow.

The two chambers keep the drives and the PSU in the lower part of the case while all of the components that generate a lot of heat are located in the top chamber. This ensures that as much air as possible can flow through to keep your GPU and CPU running without any throttling.

This case even comes with a 200 mm frontal fan installed, and it can be removed if you need the extra clearance for larger components.

Best Small Micro ATX Case


InWin 301

  • Tempered glass side panel
  • I/O panel lit by LEDs
  • Supports up to three storage drives
  • Durable construction of 1.2 mm steel

The InWin 301’s best quality is that it features a slick design that is complemented by the inclusion of an LED strip around the I/O panel, it’s also one of the smallest micro-ATX cases. Equipped with a tempered glass side panel, it’s easy to see the internal components of this case, and you won’t have to worry about scratches, like with acrylic.

Despite its small size, you can install a 240 mm fan in the front of the case and a 120 mm fan in the back. The case even comes included with a GPU support that will help prevent it from sagging, though it may be incompatible with some of the larger cards out there.

The dust filter on the underside of the case is designed to be removed quickly and easily for simple and regular cleaning.

Best Micro ATX Case for Cable Management


Phanteks Enthoo Evolv X

  • Available in three color schemes
  • Features internal cable covers
  • Can support up to 10 HDDs and 9 SSDs
  • Tempered glass side panel

The Enthoo Evolv X from Phanteks is one of the pricier options on this list, but it’s also far more capable than competing models. The interior features cable management covers and an intelligent design that is meant to ensure that air flows through every hot spot.

You can install up to 10 HDDs or 9 SSDs in this case, giving you unparalleled storage space, though the cable management will get harder with each one that is installed. This model is also ideal for liquid cooling as it comes with a radiator bracket as well as a fill and drain port.

Best Budget Micro ATX Case


Rosewill FBM-01

  • Comes included with two fans: one 80 mm and one 120 mm
  • Supports up to three storage drives
  • Dust filter on the case’s underside
  • Excellent build quality for the price

If you’re looking to save as much money as possible, Rosewill has you covered with the FBM-01. This case can support up to three drives, as it features a single external 3.5” bay and two internal ones. Each of these mounting locations can also support 2.5” hard drives and SSDs.

Unlike other cheap mATX cases, this one comes included with two cooling fans. The first fan is a 120 mm model that is mounted in the front of the case, while the second is an 80 mm fan in the rear. There are also ventilation ducts along the side and back of the case to help improve airflow.

For anyone who is looking for a cheap Micro ATX minitower this would be our pick.

The I/O panel was the only part that disappointed us, as it only features two USB 2.0 ports as well as audio in and audio out jacks.

Best Value Micro ATX Case


Thermaltake Versa H17

  • Convenient tool-free drive bay
  • Features a covered power supply
  • Cable management space behind the motherboard tray
  • Supports up to four storage drives

The Versa H17 from Thermaltake is our final product, and it’s also one of the most affordable out there. Features like a USB 3.0 port on the I/O panel and a tool-free drive bay help make this model stand out when compared to other budget Micro-ATX cases, and its build quality is also excellent.

There is even a full-length cover that helps separate the power supply from the rest of your components to maximize airflow to the rest of them. To save you even more money, this case comes with a 120 mm turbo fan already installed in the rear.

Best High Performance Micro ATX Case


Corsair Crystal 280X RGB

  • Comes in black or white
  • Comes with two 120 mm Corsair RGB fans
  • Triple tempered glass panels
  • Dual chamber design for better cable management and airflow

The Corsair Crystal 280X is another relatively pricey option on our list, and it comes installed with two 120 mm Corsair RGB fans that immensely improve how much you can customize it. Each of these fans features 16 LEDs that can be personalized individually, and they run with the help of an included RGB fan controller.

If you like seeing the inside of your computer, you’ll love that this case features three separate tempered glass panels, giving you near-complete visibility. This case is designed for optimal cooling, so you can fit either 6 120 mm fans inside of it or 3 240 mm radiators.

Best Minimal Micro ATX Case


Cooler Master MasterBox Lite 3.0

  • Features an Acrylic side panel
  • Comes included with three trim colors
  • Also comes with dust filters
  • A rear fan comes with the case

The MasterBox Lite 3.0 provides the buyer with immense value for money, which is one of the best things about the Micro-ATX form factor. This model comes equipped with a dimmed side panel that will allow your RGBs to shine through without forcing you to make your cable management perfect.

Since it comes included with dust filters, you won’t have to worry about too much dirt and debris getting inside of your case and causing thermal throttling. Another advantage is that this case comes included with a rear fan, which isn’t common at such a low price point.

One of the only things that bugged us was that there wasn’t much space to manage cables properly, so you’re going to have to do a lot of planning.
