I just love the Coolermaster Cosmos S...
It looks different, if not a little bit sporty(if sporty is the right word choice), and is well setup i'd say. Especially if you ever think of going watercooled. Lots of Space inside and you can easily mount a
240mmx 120mm Rad in the roof or the rear.
The intake fan vents have removable panels to install filters and if you're going for a Quad core then best go for Watercooled Mobo so ya can clock hell outa ya chip
