Opening the case up reveals how much room you actually have to move around it. The case supports ATX, Micro ATX, and even Extended ATX for the big boys. It will support any size PSU you can find, even the 1kw+ units. A 120, 92, or 80mm fan can be mounted in the back for your exhaust needs.
The internal 3.5 bays are sitting sideways for easy install/removal of your hard drives. This gives them a great vantage point for cooling from the huge 250mm fans. Behind the 3.5 rack are more ventilation holes, which helps those 250mm fans push that hot air out of the system. This keeps the hot air from pooling in the back of the case.
If that isn't enough, a 120mm fan can be mounted in the front for even more airflow coming across the hard drives, making sure those 1 TB drives won't overheat. The front bezel comes off relatively easy by pulling on the lower part. The wires for the front buttons don't stretch very far at all as they are held in place. Either undo them or just move the bezel out of the way. I was able to get the fan bracket out without undoing the wires.
The fan bracket is pretty standard. It unclips using a plastic release and pops right out. Mount a 120mm fan with the airflow blowing away from the bracket, as shown above. Make sure the fan power wire is on the side where the release clip is. There is a hole cut for the wire to come through the case. It will only fit through this hole.
