Those with a more robust budget who want a completely modular PC case will want to check out the Cooler Master Cosmos C700P. It's a high-end full tower with space for up to an E-ATX build, and it's made up primarily of aluminum, steel and glass. It even has a couple of handles on top for easier carrying; it isn't light or compact.

The case has built-in RGB lighting on the top and bottom, controllable on its own or capable of syncing up with other systems. Getting inside, the case has three configurable layouts thanks to completely removable parts. Cooler Master calls the three orientations regular, chimney, and inverted, and each has a completely different look through the tempered glass side panel.

The case comes with two 140mm fans up front and one 140mm fan at the back. There's room at the front and top for up to three 140mm fans, as well as two 140mm fans on the bottom. If you're going with radiators instead, you can fit up to a 420mm in the front, 360mm along the top, and 240mm along the bottom.

As for I/O, the front of the case is rather generous with USB-C 3.1 (Gen 2), four USB-A 3.0, and 3.5mm audio in and out. There are eight PCI expansion slots, as well as space for five storage drives. If you want to go all-out with your next build and you want to stick with Cooler Master, The Cosmos C700P should make a great choice.


  • Tons of versatility with multiple layouts
  • Lots of space inside
  • Built-in RGB lighting
  • High-quality aluminum and glass construction
  • Good I/O


  • Very expensive
  • It's big

Best high-end airflow: Cooler Master H500P Mesh

Airflow is important in any PC build, and most cases (if they're worth their price) will do a decent job of keeping parts cool. However, something like the Cooler Master H500P Mesh with ARGB fans takes things to the next level. It comes with a steel mesh front panel (with filter) to allow air in unimpeded, backed by two huge 200mm fans with addressable RGB lighting. There's also a pre-installed 140mm fan at the back of the case for exhaust.

The top of the case is transparent, while the side tempered glass gives a clear view of the internal hardware. If you'd like to get fancy with your GPU, seven horizontal PCI slots are joined by two vertical PCI slots. There's also room for four storage drives. This is a mid-tower, but it will fit an E-ATX build with some limited cable management if you decide to go that big.

The front of the case will fit up to a 360mm radiator if you decide to not use the built-in fans, and the top will also fit up to a 360mm rad. Otherwise you're looking at dual 200mm fans for the top. Ports are rather generous despite a lack of USB-C. The front of the case has two USB-A 3.2 (Gen 1), two USB-A 2.0, 3.5mm audio and mic jacks, and the ARGB controller. If you want a case with great airflow and have some extra money to spend, this should be a great choice.


  • Comes with two ARGB 200mm fans
  • Mesh front panel for good airflow
  • Mid tower case with lots of build room
  • Decent I/O
  • Vertical PCI slots


  • A bit pricey
  • Mesh front might add a bit of noise

Best quiet case: Cooler Master Silencio S400

Powerful gaming PCs generally create a generous amount of sound, but that doesn't mean you need to sit and listen to it while you play. Cooler Master's Silencio S400 is designed from the ground up to dampen sound, but it still allows for decent airflow. The magic is in the special sound dampening material (like foam and vinyl) installed with all side panels. The top of the case has a sound dampening cover that can be swapped out for mesh if you need extra air, and the front panel's dampening cover opens on hinges.

Adding the quiet nature of the case are two Cooler Master Silencio 120mm fans that run quietly and without rattle. For more cooling, the case supports up to two 140mm fans or a 240mm radiator at the top, and two 140mm fans or a 280mm radiator on the front. There are four PCI expansion slots, space for four 3.5-inch HDDs or 2.5-inch SSDs, and support for Mini-ITX or Micro-ATX motherboards. Front I/O is fairly simple, with two USB-A 3.2 (Gen 1), an SD card reader, and a 3.5mm headset jack.


  • It's quiet … really quiet
  • SD card reader is a nice touch
  • Lots of space for storage
  • Simple design appeal


  • Smaller size limits build
  • Might not be enough airflow for some builds

Best small form: Cooler Master NR200P

This small case is great for anyone who wants a compact build that can nevertheless put out a whole lot of power. The case is completely modular for easy tinkering, and the PSU can be mounted front or back for compatibility with Mini-ITX and Mini-DTX motherboards. It has two vertical PCI expansion slots if you'd like to turn your GPU on its side, but there are also three standard horizontal PCI slots for extra build options. The side panel comes in tempered glass and vented steel depending on what your build needs. As for storage, there's space for three 2.5-inch drives or two 3.5-inch drives.

While it comes with a couple of 120mm fans, there's actually room for seven total fans: two 120mm on the bottom, two 140mm on the back side, two 120mm on the top, and one 92mm on the back. There's even dedicated custom cooling support thanks to pump mounts inside the case. I/O is a bit limited with two USB-A 3.2 (Gen 1) and a 3.5mm headset jack, but that's expected on a tiny case like this one.


  • Beautiful compact design
  • Customizable interior
  • Decent cooling support
  • Modular design makes tinkering easy


  • I/O is a bit limited
  • Will be too cramped for many builds

Bottom line

Any of the above Cooler Master cases will make a great starting point for your next PC build or upgrade. But if we're suggesting just one, the Cooler Master Cosmos C700P has to be at the top.

It's expensive, but it's a high-end tower with room inside for a truly complex build. Built-in RGB lighting gives it some extra appeal, and there are actually three different possible layouts thanks to the modular design. There's a ton of room for cooling solutions, you'll have more than enough space for even the beefiest of graphics cards, and the I/O is generous.
