There is plenty of space on the motherboard tray for all micro and full size ATX boards with room to spare. There are even slits for attaching cable ties to keep everything tidy. The fans can be plugged directly into the motherboard or connected via adapter to a standard Molex plug. The hard drive trays snap easily around a standard 3½" drive and then slide and lock into place in any of the five available bays.
With the power supply located at the bottom, some cables may come up a bit short, especially the +12v CPU and main ATX. However I did not have any problems with this particular unit, a small Apevia 500W PSU. Larger wattage power supplies typically have longer cables, which can be routed out of sight behind the motherboard tray. The CPU socket access doesn't quite line up however it appears close enough that the backing plate could still be taken off without removing the motherboard. These square holes seem to be made more with Intel boards in mind.
Because of the beveled ends on the mesh front bay fillers, the floppy and optical drive are not flush, they are recessed slightly. This doesn't cause a problem but may be an aesthetic issue for some. With the irregularity in the shape of the bezel anyway it doesn't stick out too badly. Neither the front fan LEDs nor the top power and HDD activity lights are very bright, which is a boon for those that prefer a dark room, and the switch allows the fan LEDs to be turned off altogether.
Let's wrap up with some final thoughts on the Cooler Master HAF 922.
