This case has one external 5 ¼” bay for optical drives, coming with an aluminum bezel for the drive tray in order to hide the optical drive, as already explained. As for hard drive bays, GD04 uses a unique configuration. It has one fixed 3 ½” bay and one fixed 2.5” bay, but the third bay (the one near the rear panel) is reversible and can be used by one 3 ½” drive or by one 2.5” drive. Hard disk drives are fastened to the case using rubber rings to absorb the vibration produced by the drive and thus reducing noise level.

The reversible bay comes with a rubber flap attached to it. This flap was added to make sure that hot air follows the path the manufacturer intended it to follow.
