Although Cooler Master categorizes the Elite 360 as a mid-tower it is small enough to fit the mini-tower or desktop classification. There are only three external drive bays, two 5¼" and one 3½", and these are turned perpendicular to the base when set in a tower orientation. The left, or top panel, has ventilation holes stamped, one of which is drilled to mount an 80mm, 92mm or 120mm fan. Likewise for the top, or right side panel.
The rear of the case appears much like a standard tower with the exception that there is no cutout hole for mounting a power supply. Instead we see only a standard NEMA IEC-320 socket. Seven riser slots are available for full size ATX motherboards and mounting positions for two more 80mm exhaust fans can be found above the motherboard I/O opening. Thumbscrews are used to hold both side panels in place.
The Elite 360 actually looks a little more at home in a desktop orientation. There are stick-on rubber feet in the included accessory pack to use so you don't get the bottom panel all scratched up. At one end of the front bezel, the bottom if it's standing up, are two USB ports and microphone/headphone jacks. At the other end is the power and reset buttons, and the power and hard drive activity lights. Note that the left or bottom end of the bezel is vented, we'll find out why when we take a look inside.
