First let’s start out with my favorite part of the review, the unboxing. Taking a look at the front of the box, it is decorated with a unique picture of the case, the model of the case and also an image of an anime character. Looking at the first side, you have features listed about the case. The back side of the box is an exploded view of the case that displays the different features included in the CMT 520. The second side has all the specifications of the case listed.

Opening up the top of the box, you are presented with two large closed cell hard foam pieces that secure the case that is covered by a plastic bag.  One nice touch is that one of the box flaps shows you how to get the case outside of the box.  Rather than trying to reach in trying to grab the case, you are supposed to turn the box upside-down and lift the box off of the case.

The instructions for the case, are detailed pictures about the different features in the case.  This is black and white but is a nice touch to still include detailed instructions about the different features of the case.

A Closer Look at the Case

Starting out with the front of the case, you are greeted with a nice large tempered glass front panel that has FSP logo at the bottom.  Intake air is taken from the side and bottom of the front panel. The front I/O starts out with 2 USB 2.0 ports, HD audio ports, a large power button, a recessed reset button, an RGB selector and 2 USB 3.0 ports.

The top of the case perforated and has room for 3 X 120 mm fans.  It also has a nice large removable dust filter to keep the dust out of your case.

The right-side panel is just a solid steel panel. The side panel is secured by two small thumb screws. You won’t find any bulges or pop outs to help with cable management.  Its ok, there is plenty of room behind the motherboard tray to route cables.

The rear of the case has mount for a 120 mm fan that can be moved to make room for any clearance issues.  Then there is your rear I/O cutout, your 8 pci slots and lastly your PSU bracket.

The bottom of the case is pretty plain, with the standard PSU dust filter.  FSP provided a high-quality dust filter and not just a flimsy piece of mesh.

The left side panel is a nice large piece of tempered glass, that is secured with thumb screws.  This panel is very easy to remove and replace.

 A Closer Look at the inside

Taking a look behind the right-side panel, you notice right away there is a foam piece that is holding the wrapped PSU cover plate. You also notice that there are a lot of cut outs and tie downs to be able to manage your cables. There is also a fan hub/ RGB controller included to be able to control the 4 RGB fans that are included with the case.  Below the large CPU cut out is an SSD plate that is secured with a thumb screw.  There is also a drive cage in the PSU basement that can support two 3.5” drives.

Taking a closer look at the main chamber, you are greeted by the 4 x 120 mm RGB fans that are included, 1 in the rear and 3 placed at the front of the case.  Also, at the front of the case, there is room behind the fans and a cut out in the PSU bay that can support up to 360 mm radiator along with the fans.  You can also notice the many mounting points for reservoirs and also an area to place two more SSDs.

Above the PSU area, there is room to put a PSU plate to cover the area.  There is a nice cut out that allows you to display which PSU you are using. There are four foam pads included to make sure your PSU is elevated for increased intake. There are also nice cut outs above the PSU areas which allow easy routing of your USB and HD audio cables at the bottom of the ATX motherboard.

As previously mentioned there isn’t much of a motherboard tray due to the large CPU cut out.  Having this large cut out does weaken the integrity of the motherboard tray a slight bit, but the case is still solid as a whole, especially once the side panel are installed.

Overall, the interior is fairly standard aside from the PSU cover.  The all black interior and included LED fans brings a welcoming aesthetic that will go with almost any build.

 Test System and Build Impressions

The system being put in this case is my test bench setup.  It consists of the following parts:

  • CPU: AMD Ryzen 7 1700x
  • Motherboard: Asus Crosshair VI Hero X370
  • Memory: Gskill Ripjaws V 16gb 3200 mhz
  • GPU: MSI GTX 1050ti 4gb OC
  • CPU Cooler: FSP Windale 6
  • PSU: Corsair TX 650w

Building in this case was a joy.  There were no difficulties at all.  With the included screws and accessories and a screwdriver, I was able to put the parts above in to complete the build in great time.  Even with the large Windale 6, it was able to fit in the case with ease.

With the great aesthetics of this case, it makes almost any build complete.


  • Tempered glass side panel and front panel
  • 4 x 120 mm fans included
  • Great quality fan filters (top, front, bottom)
  • Included RGB controller/Fan hub


  • Rubber grommets not included

Overall, I’m impressed by FSP.  Their great quality from their PSUs has not only crossed over to CPU coolers, but also to cases.  Their overall great attention to detail has made the CMT 520 a competitive case in the RGB/Tempered Glass category.  If you $109 to spend in your budget, make sure to take a good look at including the CMT 520 in your build.
