Once the side doors are opened, we discover the interior of the chassis has a thickness of 1.2mm. Normal enough, we find the power supply compartment to the top of the chassis, just behind the 5 and a quarter inch bays, with the installation being done with normal screws. This part is easily accessible from the top of the case, which makes the arranging of cables and installation of peripheral devices easy.

The hard drives compartment situated at the front bottom of the case is removable, and has room for the installation of a 120mm fan. The compartment can hold up to five hard drives, but integrates no vibration absorption system or removable drawers. Installing the devices can only be done with screws. Nevertheless, the chassis perfectly absorbs the vibrations and is quiet.
Just above this, two other 3 and half inch locations can be found, and provide access to the front of the case. They can consequently host two other storage units, if you are adept at storage.
If you are no longer using 3 and a half inch peripherals, you can install devices like memory flash card readers, VFD/LCD displays, multifunction display or a fan speed controllers.
