The first thing that you notice about the case is the attractive front with USB ports located at the bottom. When you turn around the case it has the area for the PSU, this is a bracket which you simply unscrew, attach the PSU, then put back in. This design is slightly better in a way than on the Coolermasters where you have to slide the actual unit in, but at the end of the day the Coolermaster is a little more secure.
