Two problems I am seeing with this board. First, no workie when mounted upside down, all the heat will end up at the chipset, then your are screwed. That of course is a minor detail, since I havent seen all that many BTX cases running around. The second is the SATA ports. WTF!!! First they take off two of them (im assuming to provide HT bandwidth to the "southbridge") but then they stick them at the ass end of the case. WTF!!! Again most people arent going to have a problem with this, but I do happen to have 5 SATA HDs in my machine. Makes this option considerably less enticing.
