Case recommendation for H20-Apex

[Zamt]

I want to get the Swiftech H20-APEX, but my current case is simply too small, even to mount it on the back. So, I'm looking for a new case. My preferances are aluminum with a side window. I would like to mount the radiator inside the case without taking away space for drives. I also don't want a Mountain Mods case, it's too wide. Any suggestions, or am I aiming too high?
