Cooler Master Cosmos II Revealed

Before taking an in-depth look at the features, lets look at the basic specifications for the Cosmos II. As you can see it is going to be available only in a Midnight Black color, and is absolutely monolithic at 344mm x 704mm x 664mm (13.5" x 27.7" x 26.1"). This is one of the most massive cases ever released, right next to and perhaps topping the Lian-Li PC-V2120 and Silverstone TJ11 in that regard. It may also be the heaviest full tower case at 22kg or 48.5 lbs! This is due to the aluminum construction with steel used on the interior as well. It supports a wide array of motherboards, including micro-ATX, ATX, E-ATX, XL-ATX, SSI CEB, and SSI EEB. By default it is configured with three 5.25" drive bays and twelve 3.5" drive bays (two of them hot swappable).


Here is a good overall look of the case. Thank goodness for those handles, this case is massive. The brushed aluminum finish stands out along with the extruded side panels, giving you more space for cable management and large CPU coolers. You can see lots of ventilation at the front with a slide down cover concealing the 5.25" drive bays and hot swap bays. The left side handle is also ventilated, and so is the right (although not quite as much). There is a 200mm front intake fan, 120mm top fan (but you can use a 200mm fan, two 140mm fans, three 120mm fans, or a 360/280 or smaller radiator in this position), 140mm rear fan (which can be replaced by a 120mm fan), two optional 120mm side fans, an optional 120mm fan for the mid HDD cage, and two 120mm fans on the bottom HDD cage. So that's a total of five included fans, but you can use up to 10 fans on this case. Dust filters are included on every intake vent.


Here is the front with the cover slid down. It reveals three 5.25" bays which are easily removable from the front, as well as two key-locked hot swappable 3.5"/2.5" drive bays.


The I/O panel is at the top-front and includes standard audio ports, firewire, two USB 3.0 ports, and four USB 2.0 ports. At the top there is another cover that conceals the power button, reset button, as well as fan and fan LED controllers for all of the fans. Impressive!


Here you can see that the doors are designed to swing open like a luxury car.


At the rear there are 10+1 expansion slots, PSU mount which allows you to mount the PSU facing up or down, a 140mm exhaust fan, and three rubberized holes for a water cooling system's tubes or cables to pass through. Inside there is a huge CPU retention plate access hole, plenty of rubber grommeted cable management holes on the motherboard tray (and some on the compartment separator as well), secure points for zip ties and cables, tool free 5.25" buttons and 3.5"/2.5" trays, and a rubberized PSU mount. You can see that the hot swap bays occupy two 5.25" bays, and up to five hard drives can be installed in the main compartment along with six more at the bottom. The case also fits 385mm or 15.15 inch video cards.
