BitFenix Colossus is a full tower case weighing in at 18 kilograms. It measures 245mm x 582mm x 558mm (W x D x H).

There’s no doubt that Colossus is a charmer, especially with the lights turned on. LED lights can switch from blue to red and cover the front and the sides of the case.






The front panel is opened by a simple tug. BitFenix used SofTouch material for the front ant top panels, and it’s nice and soft on touch. The rest of the case, i.e. the construction and side panels are made of steel.



You can place the door the way you see fit, as you can see from the picture below.



The bottom part of the front panel has air holes for ventilation whereas the top part is reserved for five optical device spots.



The front fan comes with a large, removable dust filter. All 5.25’’ meshes are also strapped with filters.



Mounting optical devices requires removing the entire front panel and the procedure is the same when you want to clean the dust filters.



The S3 compartment can be used to store some smaller items and you’ll find its lock on the front panel.



You can lift the lid on the S3 compartment without having to remove the front panel.




The compartment hols the On/Off and reset keys, audio-out and mic-in jacks, eSATA connector, two USB 2.0 and two USB 3.0 connectors. Colossus and Colossus Venom cases come with two of each, whereas Colossus Window only comes with USB 2.0 connectors.

Lighting is controlled via the LED power key and the dual-mode key for color switching. Furthermore, Colossus is capable of incremental, dynamic changes in LED lighting intensity.

We found it pretty handy that the case comes with fan RPM controller. Apart from the two mounted 230mm fans, Colossus can take another two 140mm fans.









The back of the case reveals that the PSU is located on the bottom. Colossus has eight slots for expansion cards and four holes for water cooling systems. The rear panel does not come with any fans.  


Colossus comes with two preinstalled fans; one 230mm which draws air on the front panel and one 230mm fan that pushes hot air out the top panel.

Colossus is a massive case which is best seen when compared to other large cases such as CoolerMaster HAF-X. As you can see from the picture, HAF-X is taller than the Colossus but it is not wider.
