Caporegime
I have an AIR 540 and a Fury X, with a H105 I couldn't have the AIO at the top, but the rad is thicker than most AIO 38mm (if i remeber rightly). So it depends on which AIO you use I guess.
Now I've gone with an EK 360 L2.0, and now I'll have to do some modding if I want to go crossfire... The air 540 isn't all that watercooling friendly, if I had to choose today I would get a different case.
Nice
