Taking the left-hand side of the chassis off, we find there are two ‘levels' to the CM HAF XB. On the bottom we find 4 x 2.5″ bays, and 2 x 5.25″ bays (accessible from the front).
Removing the right-hand side of the chassis, we see space for a power supply and the 2 x 3.5″ X-Dock bays.
Removing the top gives us direct access to the inside of the chassis.
The motherboard tray can be removed to allow the installation of hard disk drives, a power supply and optical drives. This is also great if you are likely to switch motherboards, but keep everything else the same.
At the front of the chassis are 2 x 120mm CM high rpm fans which are configured in an intake position.
The X-Dock is fitted to the front of the chassis, and allows 2 x SATA HDD's to be powered by one Molex connector.
Removing the front of the chassis, we can see the Optical Drive bays and the two fans from the other side.
