Cooler Master Cosmos II Ultra Tower Gaming Case Review

The large doors on the Cosmos two swing open smoothly at the push of the latch on the back, and are easily removable due to a slotted hinge which enables the door to be lifted out the hinge mechanism.  This is great when building, as the door doesn't continuously get in the way when the case is laying on its side.  The entire vent on the door, which is capable of accommodating two 120mm fans, is fully filtered to keep dust out of your case.  This is easily the largest filter I've seen on a case, and Coolermaster's willingness to cover half of a large door in filters to ensure the prevention of dust buildup is encouraging.  The filter is also removable for quick and easy cleaning.  The locations of the vents are also not an accident, as the lower one is for the two drive bay fans, and the upper vent may fit the 120mm fans for cooling the graphics cards.

Diving right into the case, one of the most apparent aspects is the segmented interior.  We see a rather standard section with a motherboard tray, a 3.5" drive bay, and a 5.25" drive bay.  However, the bottom is sectioned off, with the bottom enclosing the power supply and up to six hard drives or SSDs.  The great aspect of this bottom bay is the thermal isolation of various components.  The power supply draws cool air from the bottom and immediately exhausts it from the back of the case, while the side fans take in cool air from the side, cool the drive, and then exhausts through the rear side panel.

The bottom drive bays are also removable, once again opening up a large amount of flexibility for the addition of fully-integrated water cooling.  The hard drive mounting is very simple, and the drive bay doors click shut to keep your hard drive stack looking as clean as the rest of your build.  The hard drives are rear mounted, so those messy cable will come out the back, where the Cosmos II allows easy cable management.  The main and lower compartments are connected by two large routing holes with high quality grommets, which may be used for water cooling tubing or for select power cables, such as PCI-E, as needed.  There's plenty of room to run the cables through the rear of the case, out of sight and out of mind.

The main compartment of the case is spacious, and will accommodate XL-ATX motherboards, quad-SLI setups of even the largest graphics cards, and an additional seven hard drives (two in the "X-dock" hot-swap bays).  There are two rows of cable management holes for further routing flexibility, and the quality of the rubber grommets is top notch.  As you can see, with everything that comes out of the box on the Cosmos II, a large number of cables are required.  The large number of ways you could run the cables, and the ability to remove unused cables really makes working with cable management a breeze with the Cosmos II.

There is also a very large CPU retention bracket hole, to ensure the best compatibility with current and future motherboard layouts.  This is a dream for anyone who swaps out or works on their CPU cooling system often.  The holes near the upper portion of the case, which are often used for the CPU power cables, are also extra large, enabling further flexibility.  The size of Coolermaster's market-first Ultra-tower really enables flexibility, and Coolermaster took advantage of that wherever they could, as they should have.  The interior looks clean in a completely all-black color scheme which is sure to please the eye of many.
