Out of the box (and you are probably going to need help for that) the very presence of the CoolerMaster Cosmos II is majestic. Describing the Cosmos II as “large and heavy” would be as much as an understatement as describing Mount Everest as “tall”. Measuring 70cm tall, 67cm deep and 35cm wide, the Cosmos II is colossal and the massive proportions of the case do not stop on the size alone; the Cosmos II weights more than 22.4kg when completely empty, a figure that will drive several people back to the gyms.
The front of the case is partly covered by a shield-like door, while the other half consists of a honeycomb metallic mesh. The front ports of the case can be seen partially exposed at the top of the faceplate. CoolerMaster’s logo can be seen at the lower middle part of the sliding door.
The sliding door covers the external bays and two small magnets secure it when closed. When open the door will cover most of the metallic mesh, yet the remaining mesh surface is more than adequate for the intake fan. There are three 5.25” covers and two locking 3.5” hot swap trays beneath the sliding door. To remove the covers one has simply to pull the plastic latch. Especially for the 3.5” hot swap tray covers, pulling open the cover will also pull the drive outwards, assisting in its easy removal.
To remove the lower part of the mesh and clean the filter you only have to pull it outwards from the bottom of the case. The blue LED 200mm intake fan is hidden beneath the mesh, cooling the top disk tray and serving as the system’s main air intake.
The front panel connectors and the case buttons can be seen at the top of the case, partially hidden by yet another sliding door. The door leaves the ports exposed but covers all of the buttons. To open the door the user has to simply push it backwards. Do NOT pull the sliding door upwards or attempt to lift the case from it as it will most certainly break off.
Beneath the top sliding door one will find the hidden front control buttons. The main power button covers the middle, with three smaller buttons installed at each of its sides. Four control the speeds of the case fans, one controls the LED lights and one is the reset button. There are also four USB 2.0 connectors, two USB 3.0 connectors, headphone and microphone jacks and an eSATA port.
When the system is powered on, the fan controller buttons light up. The fan controls have three settings, blue (minimum speed), purple (half speed) and maximum speed (red). The fan controller can handle up to 1A per channel, not per fan! Be careful about how many fans you will connect to each channel.
