BitFenix also uses the ‘other’ PCIe mounting design, but unlike the ones where I found it inconvenient with BitFenix Outlaw, this one side has a thumbscrew where you can slide the support bracket in and out. The case has a pre-installed 120mm fan and also a PSU power socket pre-installed in the case to re-route the cable to the bottom PSU mount.

The airflow in the front is routed via the top air vents on the door and it gets in through more vents that are present on the inner side of the door. The top panel has 2x 120mm mounts and a removable dust filter.  The fans can only be installed from the inside, same for the radiators.

BitFenix has a ‘heatshield’ that shields the vents in case you use the 2x 3.5″ HDD mounts on the base of the case. The shield secures itself against the case using magnets on all four corners. However, should you choose to use the bottom for installing fan/fans, there is no air filter. BitFenix could have provided an air filter, or even use the shield with an air filter attachment. bitfenix_colossus_matx_0046

BitFenix implemented four very sturdy case feet. Screws are used to secure the case feet. We’ve seen few cases with plastic push pins and even with double sided adhesives. As said before, you access the power supply’s rocker switch from the underbelly of the case. The pre-installed power cable hooks on to the power supply socket. The only inconvenience is that you cannot access the rocker switch unless you tilt the case to do so.


  1. Hoew the fuck have you mounted PSU in that case? How power cord is connected to it?
