When I put up my RIAD box it will be a totally seperate machine in it's own box connected via Gigabit ethernet. It'll run nothing but Win2k for mapping. In looking, I found it's the best (and cheapest) way to do it.

Promise makes a 4 Drive and 8 Drive ATA External RAID solution, but it's WAY too expensive. I can build a Dualie Athlon Box WITH the 1.12TB Of space and a 3Ware Escalade 7850 for cheaper then I can get the 8 Drive Promise alone.
