Cooler Master MasterCase H100 Case Review

System Build & Installation

Below is a list of the hardware included in this build:

  • MSI H310I Pro
  • Intel i5-8600K
  • Cooler Master i71C
  • 2 x 8GB Team Group T1 Gaming DDR4
  • Corsair HX750i
  • Corsair Force 120GB SSD

The Cooler Master H100 now takes the crown for the smallest case I have built in with it being 8.5” wide, 12” inches long and 12” inches high. Even though it is a really small case to build in, it actually was quite painless since I accounted for all the possible clearances with the CPU cooler and GPU.

With the PSU covering the CPU entirely, I only had 83mm of clearance to work at the back of the PSU and CPU socket. Knowing this, I couldn’t use my normal air cooler: the Hyper 212 Evo, and opted for the much smaller i71C, measuring in at a height of only 60mm.

Since this build will be a dedicated media PC, the GPU clearance wasn’t an issue as it will use the onboard graphics of the 8600K. If we were building a portable gaming rig, you would have to grab a mini card as the H100 only has 210mm of clearance for a GPU. This clearance is even reduced more to 180mm if you choose to go with a front radiator.

The hardest part of the whole build was installing the last component which was the PSU. Attaching the PSU to the case was easy but managing the extra slack of the cables was a different story. Due to the H100 size, it leaves very little room to work in when trying to place cables. Finding places where the cables didn’t interfere with the front 200mm fan and the fan from the PSU cooler was quite the task. One saving grace with not installing a PSU, was that it did give us some extra space at the bottom and that was one less cable for us to manage.

Personally, I think the H100 has a well thought out design and with knowing the clearance limitations going into the build, it was a breeze to put together.

I’m a huge fan of Cooler Master’s 200mm RGB fan and it really makes the H100 pop.
