Cooler Master Cosmos S
 

The Cooler Master Cosmos S is the "sport" variant of the original Cosmos chassis. Coolermaster has taken various aspects of the Stacker series and fused them with the original Cosmos case. The door is gone and the plastic top has been redesigned to fit a triple radiator of your choice. The new Cosmos S is also made of Aluminum which makes it much lighter.
