I am thinking about upgrading my asus z87 rog hero to a newer z97 motherboard. but I am concerned about how high up on the motherboard the ram slots will be. because I have a corsair h100i and I only have about 1/4mm in between my ram and the corsair h100i 120mm fan. do all z87 and z97 motherboards have the ram slots located at the same exact spot on the motherboard ? or do some z87 and z97 motherboards have ram slots a little closer to the top edge of the board then others ?
