Cooler Master COSMOS S

Inside, we get a gander at all that room. While there is plenty of room for your current ATX factor PC, there is also that much more space for the eATX, as well.

Ventilation will not be any problem considering the entire front uses ventilated slot covers which are very easy to remove. I should also note that inserting a DVD drive is a snap without removing the front panel since the sides are hinged allowing two finger removal of the drive-bay covers.

There is a large 140MM ventilated and filtered opening under the power supply so it can draw in fresh air along with a filtered 120MM optional fan on the bottom of the case.

On the top, there is not only room for 3 120MM fans, but they are properly spaced so you could easily mount a triple 120MM water-cooling radiator inside the case.

To the rear, there is a single 120MM fan and lots of extra holes for even more cooling potential.

To take it even further, they opened up the side panel and installed a 200MM fan to pull lots and lots of air across your video cards.

It is very safe to assume that your system, no matter how hot or overclocked, will get plenty of airflow. Considering all the cutouts to facilitate running the wiring behind the motherboard area, there is very little to impede the airflow. I really got the feeling that they took the time to lay this case out quite well. Time to install some parts!
