BitFenix Colossus Mini-ITX and Micro-ATX Chassis Review

Complete System

The Micro-ATX build took an hour to put together, twice as long as the mini-ITX build. To put it bluntly, the Micro-ATX chassis is a complete pain in the butt to work with. However, despite it’s annoying build process, the final product looks pretty god.

There’s a tiny bit of room behind the motherboard for cable routing, but there’s also plenty of extra cable space at the side of the PSU which you can use to cram excess cables.

The M12II Evo Seasonic PSU we’ve used is a little tall, especially once you factor in the modular cable connectors, as they cause a little conflict with the graphics card; the card is lifted up ever so slightly at the back.

There’s plenty of room here for a large CPU cooler and enough space to fit a small AIO water cooler if you wanted. If you need extra storage, you can remove the bottom fan and mount drives directly to the base of the chassis.

There is just enough room here for a dual GPU setup, but there’s very little space for the first card to pull extra airflow; I’d rather have two low RPM fans mounted in the top and stick with a single GPU for this reason.

Out Sapphire R9 270X is a long graphics card, so I had to remove the 5.25″ bracket from the front of the chassis to accommodate it.
