coolermaster_cosmos_s_1Our last gaming case that we reviewed was the Antec Nine Hundred Two, which was the latest revision of the award winning Antec 900, but we may have found a contender for the hearst of the average gaming system builder with the latest case from Cooler Master: the Cosmos S full tower gaming case.

In regards to aesthetics, the Cooler Master Cosmos S has to be at the top of the list for looks, with a sleek black and silver paint job and impressive carry handles and feet that run the length of the case.  The front ports on the case are carefully hidden behind a black gloss sliding cover and the power button comes in the form of a touch sensitive recess.  What really amazed us though was the level of packaging - we're used to unpacking high end components, however, we didn't really expect to see a case arrive in a protective drawstring cloth bag in addition to the normal polystyrene and plastic coverings.

Access to the case is provided through a very simple and nifty push button release system that drops the panels out sideways from the case and everything else in the case is accessed or held in an equally simple manner, with only minimal tool use required.

coolermaster_cosmos_s_2Cooling-wise the Cosmos S comes with three 120mm fans as standard: one at the back of the case, one on the top and a third located on the front of the hard drive cage.  Finally there is a huge 200mm fan located on the side panel which can provide a serious amount of airflow over the motherboard.  Thoughtfully, Cooler Master have provided an air filter at the base of the case to protect the air intake for an installed power supply, and since the case is raised away from the ground by the feet, there shouldn't greatly impede airflow.  Inside there is plenty of room to work (this is a big case: (W) 266 x (H) 598 x (D) 628 mm) and there is easily enough room to accomodate a water cooling system internally, although if you still don't think you have enough room, there are rubber lined ports for pipework through the rear of the case for an external radiator.

coolermaster_cosmos_s_3Installation of the motherboard is similar to other cases, however, Cooler Master handily include a sheet of cardboard in place of the motherboard tray that details the positions for the correct screws for different motherboard setups (anything up to Extended ATX).  As mentioned previously, 5.25" drives are installed simply by sliding them into place and pushing in the locking buttons, and HDDs are installed in the dedicated HDD cage, albeit using the common screw to locate them in place.  Cable routing was very simple, and we particularly liked the slight angling of the edge of the motherboard tray with channels for cable routing that make the job so much easier.

In testing, we found the case was very quiet, certainly quieter than our Antec 1200 case that we use at the moment, with the case fans barely registering above the noise of the installed components cooling fans.  The "lighting scheme" is provided through a red LED in the front 120mm fan and a simple red led below the I/O panel (which provides four USB 2.0 , one IEEE 1394, one eSATA, one MIC, and audio out - more than your typical case provides!)

In our opinion, the Cooler Master Cosmos S would provide an excellent enclosure for any system (escpecially a water cooled setup) with an almost tool-less build, and excellent accessability, combined with low noise levels and well designed ariflow design.  The case is clearly a cut above the majority of gamers cases and aims to compromise between cooling and noise, but the price tag is also a cut above the rest at ~£140 (at the time of writing).  Despite this, if you love the looks, this case will doubtless last your next few system builds without a problem.
