On the rear left, we spot the single fan, obviously the rear exhaust fan which is a 120 mm fan, it uses black cabling for the fans and wiring overall. And all the way down, the power supply compartment. The chassis has 7 PCI slots and thus fits up-to-EATX motherboards.
As shown on the previous page, you can mount four SSDs at the backside. Look at the space for the power supply btw, I wish the HDD cage would have been positioned a bit more to the left. You can house four SSDs and two HDDs.
