At the bottom is the PSU mount that comes with a mounting bracket. I encountered a slight hiccup when I mounted the PSU on the bracket and attempted to secure it to the case.
After meddling with the installation for a few minutes, I finally figured out the problem was that the padding to support the PSU was very thick, thus leading to the imbalance that makes it near impossible to secure the screw.
I figured out a workaround and that is to place the PSU into the casing WITHOUT mounting it on the plate. After that I secured the plate to chassis and finally, secure the PSU to the plate. As you can see, that quite defeats the purpose of the mounting plate.
One thing I hope Cooler Master improves on is the nature of the mounting plate – the screws are so short it could barely secure the plate properly. Should the ridges of the screw be damaged, there’s no way for the plate to be secure.
At the bottom the MasterCase 5 comes with 4 reasonably long rubber feet for secure footing.
Now for the interior – the MasterCase 5 is spacious, the interior is split into 2 areas and that’s one for the key components while the lower section is for the PSU, cable management and additional drive bays. Rubber grommets are found on every cutout.
Here’s the upper corner, it comes with a 140mm fan pre-installed and the cut-out is huge. There’s also sufficient room between the board and the top of the casing and that helps a lot when it comes to cable management.
Towards the front of the interior are the drive cages, they are removable.
Drive bays are also available at panel just above the PSU.
