Okay by raid u mean raid 0?
And about setting it up. Attaching the hardware is as easy as with the IDE hdds. U have to install the sata drivers BEFORE u install windows. To do this insert the windows cd and boot from it. Then in the very beginning it will ask u to press f3 (I think) to install a third party controller. Press f3 and it should take u to the setup.
I have never done this myself so some of the info might be wrong, so please correct me if u find any mistakes.
