WARNING: Reading about the NZXT Tempest may increase desire to build new gaming rig.
With that out of the way, the NZXT Tempest is hands down one of the best looking performance cases I've seen in a while. If the name Tempest didn't give you any indication to this case's specialty, then perhaps calling it the King of Airflow will help. You're looking at 6 fans pre-installed within the case (dual 120mm intake fans, dual 140mm exhaust fans, and two additional side and rear 120mm fans) coupled with several holes drilled inside of the case allow for much of the wiring to go behind the motherboard. Your system will have never run cooler (unless you took off your liquid nitrogen cooling system of course).
The NZXT Tempest is an E-ATX case, allowing for you to easily fit the newest line of video cards into this case without cramming it in. And don't forget, all 8 of your hard drives can fit into it's dual 120mm fan server style housing too.
If you need a new case or are planning on building a new gaming rig, you should definitely invest the money into a NZXT Tempest.
