A Closer Look – From the Outside (Cont’d)The left side panel incorporates a large mesh opening, which is fitted with a 200mm intake fan designed to blow air in over the video cards and motherboard. This is an area where some people felt the Cosmos 1000 needed improvement and Cooler Master responded with an active cooling solution.
The large side-panel fan is rated for up to 150 CFM at 900 rpm. As we will see later, this fan may be a little noisy for some silent-PC users and unfortunately there is no bundled speed control.
Moving around to the back side of the enclosure reveals a typical mid-tower ATX style layout except the power supply is mounted at the bottom. I like this arrangement because it keeps the center of gravity low. The back panel offers good case ventilation and is fitted with one 120mm exhaust fan.
Located near the top of the back panel are two release levers for the side panels. Lifting up the lever releases the corresponding side panel, however you may have to rock the case a little to get the side panel to fall away because there are no raised surfaces to grab on to. The two holes fitted with the black plastic inserts are for routing hoses to an external cooling system. You can also see the single thumb screw that secures the top panel.
And finally we have the right side view. Nothing much to see over here other than sleek styling and a nice looking finish.
Note: The original Cosmos 1000 used sound deadening foam on the insides of both side panels. The Cosmos S does not.
