I'd just like to say thanks to OrangePeel for starting this thread as well as the other folks on the forum for posting their builds and experience. Through this post (and others) I built an AMD ESXi machine using the info provided here. It went live over the weekend. AMD FX 6100 processor, ASRock 970 Extreme 4, M1015 all stuffed into an iStar Rackount case. The only hiccup was flashing the M1015 card where I had to use another MB as the ASRock gave me a PAL error.
