RAID 0 is also known as 'striping'.
it is the process of linking two disks to act as one essentially, writing half the data to each disk simultaniously, thus boosting speed by double.
so essentially, two 7,500RPM 500GB Drives, theoretically would behave like a 15,000RPM 1TB (in theory).
firstly, if you are installing the RAID setup WHILE installing the OS, i believe it is f6 to install RAID drivers, usually from a FDD but i believe it can be done with a USB stick or similar.
Plug the SATA disks into SATA0 and SATA1 on the mobo.
if you're striping inside windows, which i doubt since you said 'install' OS on it, then it is done in computer management. Might be an idea to give it a go on a VM to get the hang of it.
Computer Management -> Disk Management -> RightClick disk in the label box and convert to dynamic (do to both disks) -> New Striped Volume -> follow the wizard.
i hope i helped a little, i dont have much experience myself with doing it, only in theory for my A+ and MCITP.
oh and, you only need 2 disks to stripe, they will act as one disk.
a little more on basic RAIDing:
RAID0 = Striping (x2 speed increase. no fault tolerance. i.e. if one breaks, the RAID setup isnt going to function as there is only one disk remaining)
RAID1 = Mirroring (exact copy of disk, used alot in servers)
RAID5 = Striping with Parity (3 or more disks, if one breaks, the others (2 or more) can carry on being striped.)
also RAID10, which i believe is a mirrored striped volume? or something like that. sorry im just ramblinh

not ALMOST x2, exactly x2 in most cases.
EDIT: just flicked over to 7 pro, had a look, it gives options for all mentioned RAID types in the Computer management page when the labelled area is right clicked.
so it seems Microsoft might have added support for RAID-5 in 7, it used to require a 3rd party RAID controller.
