First of all let me tell you how excited I am to be a part of this program!
I'll be using a Gigabyte dual processor board with an onboard Promise RAID controller and also an LSI RAID controller currently configured with four 80GB SATA drives in RAID 5. Although I haven't read all of the system requirements I do understand that RAID is not recommended. Does that mean I should configure all drives as independent disks (JBOD) and let WHS do the rest? This so cool!
