Summary: I have just lost a week of work!!!!!!!! THE BOARD GROUNDS OUT ON THE MOUNTING STUDS!!!!!! Also what they do not tell you about this board is it does NOT support RAID drive configuration for one thing!!!!! The big issue is that the board grounds out and kills your drives. Their support people do not tell you this and try to blame it on the power supply. This cost me a couple of days to get a new supply only to have the board not work.
