What motherboard is a tough question. It's either going to be an Asus P4P800-VM (if I can find someone selling it) or an AsRock P4i865G. See, it depends because the orientation of the bracket differs for the two motherboards. I already have a Zalman 7000B AlCu, but the cases I want to get may not have enough room between the cooler and the PSU. I want to convert my non-OC ATX system to a mATX. I am seriously considering an Evercase 3505 b/c it is small. cheap and has room for 2 120mm fans.
