Inside The BitFenix Colossus Window Full Tower Case
Inside the chassis there is an all black theme here. Every bit is painted or molded in black plastic to work inside the chassis. The wiring gets tied together and secured in the tray for shipping. The hardware can be found strapped in the optical drive bays.
Behind the 230mm intake fan you have the drive bays. Five at the top will house 5.25" drives, one of which with an included tray can convert for a floppy drive. Below there is room for up to seven 3.5" drives, and with the holes in the trays you can also use them to mount 2.5" drives.
The motherboard tray comes with a few risers already in place, and depending on the motherboard type, the holes are clearly labeled to install the others if needed. The fest of the tray consists of a large CPU access hole with seven wire management holes with grommets and sixteen tabs to tie wires to.
It is a bit easier to see the 120/140mm mounting holes in the rear of the chassis from this angle. Below that you will find large plastic levers to lock expansion cards in place. These do make getting the lower two screws in an ATX motherboard troublesome, but not impossible.
All of the front I/O and fan LED wiring all gets routed behind the motherboard tray from the factory. At this point you just have to tidy up the wiring and route all of these long cables to where they need to go.
There is a built in LED controller for the chassis that also works with the Spectre LED fans from BitFenix. Do be sure to check out the wiring here in the manual, I found mine was not plugged in correctly.
