A Closer Look - Inside

A welcome addition to the Cosmos S, is a large, 200 mm fan on the side panel. On top of that the entire metal mesh has been covered by a fine cloth, which acts as a dust filter. The fan can be connected directly to the mainboard or powered by the power supply. It pushes 150 CFM at a very low, near silent noise level. This is perfect for multi-GPU rigs. The case itself is incredibly spacious. The mainboard has several holes to route cables through.


The PSU bay is still the same as in the original Cosmos. It is lined with a thin layer of foam, to dampen any vibrations. A removable dust filter covers the air vent. The expansion slots are covered by seperate, SECC covers which are secured by thumb screws. Above that is another 120 mm fan.


The hard drive cage, which can hold four drives It is held in place by one push lock and two screws on either side. The locking mechanism is incredibly simple. Just push to lock and push once more to unlock the drive. The system is single-sided, so you should still use at least one screw on the other side to completely secure your drives.


Another 120 mm fan is located up top, right where the PSU would be in traditonal cases. You can install a total of seven fans in the system, even the bottom of the case. This position also has a dust filter, which can be removed.


All four included fans use mainboard headers, but also come with adapters to power them via Molex plugs. Cooler Master also decided to color code the mainboard headers for Audio. HD Audio is orange, while the AC'97 connector is black. The power button is very unusual as well, it is fed directly into the 24 pin power connector. As you can see, there is actually three cables instead of two.


Taking the hard drive cage out is done easily through the front of the case. It has a very strong resemblance to the one used in the Stacker series, but instead of SECC, it is made completely of Aluminum. Installing a hard drive in it is done the traditional way with four screws.
