It does support RAID actually (RAID 0, 1, 5, 0+1, and JBOD). I've just chosen not to use it.
I do have a small issue with this system that I am unable to pinpoint. Sometimes the system will freeze for a few seconds, then a beep from the PC speaker and then resume normally.
I thought the Kingston RAM would've fixed it but apparently not (the OCZ RAM I was using wasn't playing well with the system).
I'd like to fix this issue, I MAY change motherboards, but that's the last resort. I do use my Dell Inspirion 6400 laptop more then a desktop so for now it sits off.
