Yeah, no way a thicker rad would fit up top very well. I'm not sure any rad would fit up front with the 30mm thick stock fan, I could put 25mm's up there and fit one. But I'm just gonna drll the rivets and move the HDD cage back 1/2" inch. Wish they made a 200mm rad, could toss that up front, but in the future, most likely will be a PA160.1 up there, and then a 140.1 rad down below, and could still fit a 120 on the back. Another funny thing is, a 480mm rad would actually fit up top. Thats really an insane amount of rad in a mid tower. Yeah the GD-70 is ownage. I'm liking this midtower the more I look at it, was thinking HAF 932, but this is a bit more of a challenge, and once I got all this internal, it's just going to be much more cool as people don't take this route with mid towers. Also I'm not sure if there are any other internal WC looped 922's, I have searched high and low and found nothing but ap ic of a rad in one.
