Eh... make sure you install windows BEFORE installing that PCI-E RAID card in your motherboard. If you do it the other way around, you're going to have issues with windows recognizing the RAID array.
UNLESS you're booting Windows from the RAID array. But if you're doing that, Windows will most likely give you all kinds of issues because you changed motherboards and probably chipsets. In that case you'll need to back up everything on something else and format the RAID array.
Make sense?
