The Interior of the Cooler Master MasterCase 5

Much like the exterior, the interior of the MasterCase 5 is entirely black as well. Every part, with the sole exception of the motherboard's standoffs, is black. The metallic surfaces are sprayed with the same satin black paint as the exterior, while the few plastic parts are slightly glossy. A large rectangular hole is cut on the motherboard's tray to allow for the installation of aftermarket coolers without having to remove the motherboard.

A metal floor separates the system area from the PSU compartment. This floor is permanently attached to the frame and cannot be removed, which is not exactly great for a modular case that boasts maximum flexibility. However, it is necessary for the mechanical cohesion of the case, as the mechanical strength of the body is not great, especially for a case with two carrying handles. If not for the metallic floor, the rest of the chassis would be prone to twisting/bending.

There are two holes on the floor, covered with rubber grommets, for the routing of cables, as well as an opening near the front for the installation of liquid cooling radiators. There are also two slots for the "slip-and-clip" SSD pockets. Each pocket is held in place by a thumbscrew.

Each of the expansion slot covers is vented and held in place with a thumbscrew. The lowermost cover is different and can serve as an exit for up to three cables. To minimize the chances of pulling/damaging the cables when moving the case, they can be locked by twisting them over the hook next to the hole.

As the metal floor is fixed to the case, the PSU can only be installed by sliding it in from the rear of the case. Four thumbscrews hold the PSU cover in place. Cooler Master installed two rails that the PSU slides and sits upon once inserted. To insure that there will be adequate and proper air intake regardless of the power and position of the PSU's fan, the designer perforated the floor beneath the PSU all the way down to the center of the case. A metal stand is located in the PSU compartment, near the front of the case. It serves as a stand for a dual bay drive cage, if there is one installed, and can be removed to make room for a liquid cooling radiator.


Only one dual drive cage is installed in the standard version of the MasterCase 5. The user can move it vertically to any height between the top of the case and the compartment's floor, install it inside the PSU compartment, or even remove it completely. The 5.25" cage has convenient plastic lever locks for the devices. If desired, the 5.25" can be removed, allowing for the installation of a third front intake fan and or the installation of a 3.5" devices cage instead.


With the removal of the faceplate, virtually only the frame of the MasterCase 5 remains. The intake fans are installed from the front side of the case but there is not enough room for a radiator there. Liquid cooling radiators can be installed only to the inside of the case. Although the removal of the drive cages allows for the installation of three intake fans, a triple radiator is unlikely to fit, as its extra height will bump to the top of the case.

The radiators of all-in-one liquid cooling solutions should easily fit in the lowermost part of the case but beware of other solutions that may be too wide or thick. Also, do note that the presence of a radiator obviously denies the installation of a drive cage. A 240/280 mm radiator requires the removal of the metal stand in the PSU compartment as well.

The rear of the motherboard tray is all black as well. We can see two more slots for the "slip-and-clip" SSD pockets here but there are no pockets installed from the factory. Only two are provided with the case and can be installed on either the main compartment's floor or here. If more are required, Cooler Master is offering them as extras for $5 each. The clearance of 23.6 mm (0.93") is plenty for the easy routing of cables and the cable straps to the left aid cable management a lot. The only issue is that the presence of the SSD slots prevented the creation of cable tie mounting joints. There are only a couple of mounting joints located near the back of the case.


For the means of this review, we installed a Corsair AX760i with the red cable set, for strong visual contrast. It fits without issues inside the MasterCase 5 and the cables are long enough for a standard system. Still, do note that the CPU power cable is not long enough to be secured with cable ties across the edge of the motherboard tray, at least not without placing a lot of stress on the connectors. Other than that, cable management is easy and the design of the MasterCase 5 does help with cable management a lot.


A standard ATX system comfortably fits inside the system area of the MasterCase 5, even with the extra drive cages installed. However, cards longer than 29 cm (11.4") will not fit with a drive cage installed in front of them. Without a radiator installed, the maximum length of an expansion card is 41 cm (16.1"). If a radiator is installed, its thickness needs to be subtracted from this clearance. Up to a 280 mm radiator can be installed at the top of the case only if the extra top cover is purchased and installed and still we would not recommend the installation of a radiator thicker than 30 mm. Without the top cover, there is not enough clearance for a liquid cooling radiator, only for two fans.

    Their Node 304 is fantastic. I was able to move all 6 of my 3.5" drives from my previous midtower case into that little box, plus a pair of 2.5" SSDs I wedged on the floor. Granted, you'd have to remove a pair of 3.5" drives if you wanted to throw in a PCIe card, but the fact you have that ability in something so small is fantastic in my opinion.

    You don't even need to wedge the SSDs on the floor. You can attach them to the two outer 3.5" mounts (so in between the case door and the drive mount).

    Node 304 is pretty large at 19.5L. It can accommodate large video cards and a 14cm double tower cooler.

    Node 202 (new) is a failed design. Absolutely terrible cooling performance for what it can pack.

    For ITX, Silverstone, hands down.
    RVZ01/FTZ01: 14L, can pack some high power parts and still remain cool.
    RVZ02/ML08: 12L, slimmer version of the above, but still allows for high power parts.
    SG13: 11.5L, very difficult to top this case.

    Agree on Silverstone - I love my little SUGO SG05!

    So using your logic, the only car anybody in the world should be buying is a Honda Accord (Which has been on Car and Driver's 10 best list 29 times). Do you want every car company in the world to only make copies of the Accord?

    Both are designed to meet consumer needs while increasing revenue. It's a lot like buying parts of a video game, a little at a time until your total cost is far greater than just a game.

    I'm not sure what to think about this computer case. I would have to build a computer with it before I could give a proper opinion.
  • usernametaken76 - Thursday, August 27, 2015 - link

    Isn't that the point of reading multiple reviews before making a purchase? Of course after purchase anyone and everyone is entitled to their opinion, but what's the point of stating the obvious?
  • jabber - Thursday, August 27, 2015 - link

    I so love dusty perspex windows. How very last decade.
  • theduckofdeath - Saturday, September 12, 2015 - link

    The custom water cooling mods are getting more popular these days, which would justify putting a windows on it. Personally I'm happy with just having a padded metal lid, like on my Silencio 352, for the silence and also not having to see the cable mess I aways leave in my PC. :D
