But it's tall enough that I don't know if it will actually fit in that case... Any help would be appreciated.
Hope I'm not too late, but I am using an Antec Kuhler 620 water cooling and it fits in fine this case. I think the Corsair H60? will fit the same way. Anyway what I did was mount the radiator/fan to the bottom front intake case fan. I even have it push/pull + radiator and a 12" GPU could still fit in it as I measured it. Right now I have a GTX 570 in it and that's about 10.5" long with room to spare between the p/p radiator. I can't help you with air but since you mentioned the H50/70 figured you would be open to water options.
Here's my setup when I had the MSI 6870 which is actually a really long card too, like 10". But yeah I measured with a tape measure and to hit the fan it would be just over 12" so your options are all really there for any GPU's.
Yeah I went with the noctua and it fits fine. I actually could have probably gone with a larger fan but right now my cpu temps are at 65 under load stressing all 4 cores when processing 110 fps, if I turn on vertical sync it runs a cool 55c constantly and that's at 4.6 ghz overclock. Must say am pretty happy.
