When we move upwards a little we can see a 120mm fan, this one is 1200 RPM rated at 17 DBa. Again everywhere, meshed aluminum.

Slightly above the rear fan, two holes; for water-cooling tubes should you require it.

All the way at the top of the chassis something very interesting is going on,; especially with water-cooling in mind. You can place three fans in there yet since there's no PSU ... what would you mount up there? Exactly, you can pretty easily mount a tripple 120mm radiator for watercooling there, in fact it's prepared for that, look at the mounting holes. Excellent!

One fan is pre-applied for you, 120mm/1200 RPM.

Moving onwards to the lower front; here we see the drive bay. Now the original design had these nifty drive cages, they are gone. This is a more traditional mount. Though you have more space this way, cables however will be everywhere. I think I like that older drive-cage idea better.
