Installing the PSU requires you to fasten this mounting plate to the back of your PSU first. Once the four screws are tightened, the PSU slides into the opening and is held in with four thumbscrews. This makes it easier when you need to alter or replace an item in the system later on. CM provided the V750 for this review build because it was designed specifically for builds that are limited in space. It comes in with a shortened length on 140mm. The Colossus ITX can support up to the standard 160mm PSU size.
Bitfenix provided us with two Spectre Pro red LED fans for this project to add some additional lighting.
The silver square towards the bottom of the front bezel is the LED source for the LiteTrak system.
Building in the Colossus is pretty straight forward. There really isn’t much internal space to offer different installation options; you install a single size board in a single mounting location. There are cut outs and pathways where some of the power cables run, but other than that, you are limited on cable management. This isn’t necessarily a bad thing considering the confined space. Ninety percent of the cables will end up on the same side of the case, opposite side of the GPU, insuring there is the least amount of air flow interference.
We used a smaller GPU for this build, but the Colossus can support GPUs up to 330mm in length once the HDD cage is removed. The PCI-e power cable was run from under the platform and tucked between the GPU and memory to keep cable runs as tidy as possible.
