Special Carriages For Hard Drives
The installation of the 3.5" hard drives is simple but ingenious. Two individually removable installation cages can be disconnected from the case interior with an individual latch. Each cube easily accommodates three drives. To cool these drives, there is a plastic bracket for an 80 mm fan on the back of the metal frame. That fan's only job is to cool the hard drives.
The Revoltec/Chieftec case houses two HDD carriages
Each of the carriages can be removed to install the drives.
