I have a z77a-g45 mobo (1155 socket) in an Antec 1100, with some HyperX with very large heat sinks on them (t1 series). I have one RAM slot available if I need to move the cards over one, but the stock fan is very close to the RAM slots, it appears to be within a centimeter of the cards. I'm not very concerned about headroom as the 1100 seems to have plenty, but the height of my RAM's heat sinks and their proximity to the stock cooler worries me. Does anyone have experience with this board, or RAM and know what I could fit on this thing? Any help that can be given is greatly appreciated.
