Just a warning. I built a box from this board. It was unstable as hell with a 340 W PS, so I bought the 430 W Enermax everyone swears by, it was still unstable as hell. The board has serious bios issues with recognizing CD Drives even with latest revision. Once it stops booting, clearing bios and resetting then booting under incorrect speed first and then boosting to correct speed (not overclocked) was the only way to get it to boot.
I also built one at the same time, identical in every component except with non-raid Mobo. It also is quirky, but usable. The Zip Drive seems to forget how to read disks formatted on other machines and the A: drive has similar issues. But, it currently is being used, whereas the Raid box is sitting by my feet.
I'm currently waiting on a new board, and wouldn't touch a KG if you paid me.
