Cooler Master Cosmos II Case Review

Inside the Cooler Master Cosmos II

The Cooler Master Cosmos II supports E-ATX, XL-ATX, SSI CEB, and SSI EEB motherboards, but not HPTX models. The motherboard tray has a huge hole for you to access the backplate of the CPU coolers without having to remove the motherboard from the case, several holes for you to route cables behind it, and several clips for you to fasten cables using cable ties.

For better thermal management, the interior of the Cosmos II is divided into two compartments: the motherboard compartment, where the upper hard drive cage is also located, and the power supply compartment, where the other two hard drive cages are located, behind the two 120 mm fans you see in Figure 17.

In Figure 19, we have another overall look inside the case. Expansion cards are fastened using thumbscrews. The Cooler Master Cosmos II supports video cards up to 15.1” (385 mm) long and CPU coolers up to 7.5” (190 mm) tall.

You can install a 120 mm fan on the side of the upper hard drive cage to cool down the motherboard compartment. There are two possible positions for this fan.

The power supply is installed at the bottom of the case. It can be installed with either its bottom fan facing up or facing down, so you can decide if you want the fan of your power supply pulling air from inside the case or from outside of it. As already discussed, the case comes with an air filter for the power supply fan. Because this case comes with an extender on its rear panel, you can install power supplies up to 9.8” (250 mm) deep.
