• Very versatile 3.5″ mounting cage. Each can be individually removed and are secured by three thumbscrews each
• Each 3.5″ HDD cage can also support two 2.5″ drives
• 90-degree SATA cable unusable because the center thumbscrews are on the way. Users must plug-in a straight angle SATA cable instead.

5.25″ installation:

• Drive bay cage can be removed entirely to make way for additional radiator clearance, additional fan mounting or 3.5″ drive cage position.

2.5″ installation:

• One can be installed behind the motherboard tray
• Two can be installed inside each 3.5″ HDD cage (one on top and one upside down)

Cable management:

• There is no shortage of cable management options behind the motherboard tray
• The entire top and bottom area is open so cables can freely pass through.
• An additional grommet is privided to cover one of the 3.5″ drive bay areas if the builder wants to use it as a pass-through point instead.
