This is the 800d, the light showing through is just because I didn't have the sides on. All of the wiring runs through the backside so the airflow is absolutely awesome in the case. There is so much room, I haven't had the chance to put mine on water yet. I am running 4.2 ghz stable on air though no problems, I could probably go higher if I messed with it a while. There's room for 3x120mm radiator at the top of the case, also there is a 4x sata hotswap bay in the front.
Here's a little better shot of the wiring.
