With an overclocked i7 and two GPUs spitting out around 200w @ stock speeds?
Should seriously consider a 240 + 360 rad...240 + 240 at minimum, but this isn't likely going to fit into the plan if you don't want to mod the case. Not sure if you can squeeze that much rad into that case. Maybe a thick 240 and a thick 140 or a thick 240 and a good 200mm?
Okay, what if I were to do this.
The green represents the radiators I would put in it. On the top and front of the case would be 240mm and he back one would be a 120mm rad.
The red hard drive racks I would remove and put my harddrives in the orange spots. 2 HDD's in the optical bays and 1 SSD near the PSU. It's a Samsung 830 so it would look nice.
And the purple would be my pump+res combo
