The case has five removable HDD racks on the bottom of the case front. To install a HDD simply pull out the lever, insert the HDD into the rack and close the lever. Pretty easy to do and Cooler Master is the only case manufacturer to do it this way. The case is deep enough to install a long video card such as the GTX280 without issue as to length inside the case. In front of the HDD racks is the area for a 230mm fan.

The motherboard area is fitted with an insert showing which mounting hole to screw in the standoffs and screws for which motherboard configuration. One thing about the mounting guide is it is made out of paper and meant to be removed before mounting the motherboard. Three form factors are supported, Mini-ATX, ATX, and extended ATX. Just follow the letters on the guide and you should have no issues.

The motherboard add-in card area holds seven expansion slot holes. Each has a patented, no-screw lock that is easy to use. Just lift the lock up and the add-in card can be removed from the motherboard. Flip it back down to lock the add-in card into place. The case btw has plenty of room as we’ll see in the system build page of the review. There are five holes around the case perimeter to route cables from the add-on devices and drives. Depending on the length of the PSU, one of the holes may be blocked by a long PSU. There are plenty of holes for effective cable management of a system.
