*should* be fine, it wont be any wider than 3 slots, you could try a different mobo with the PCIe x16 slots further apart (gonna want at least 8x and 8x), as the case is full tower and the mobo is mini ATX you'll have PLENTY of room between the bottom gpu an the PSU.
Thanks mate! What other mobos are there that have the features of the P8Z68 but with PCIe slots further apart? I really like the features the P8Z68 is packing. I don't understand what you mean by 8x and 8x, could you explain please.
