Dang man. That looks like it has just awesome airflow through it. I imagine that if you get that, you'll have NO problems maintaining a cool system with some good airflow. Not to mention that if you want to do water cooling, it has holes in it for that very thing.
Only thing is that it looks pretty big. The dimensions are big and you'll want to make sure you have room for that beast!
