You could, but the install won't last long, since you will have to activate the OS within a certain number of days, and I seriously doubt the activation will work, and you'll have wasted a lot of time, since it will be unusable. The Dell XP versions are linked to the specific motherboards, I believe. I have two that came with XP pre-installed, and an older machine for which I bought a non-Dell OEM version of XP. The latter asks for re-activation at the drop of a hat; I put a new video card in it yesterday, and as soon as I booted, it told me I had to reactivate. On the Dells with the original install, I've changed/switched hardware several times, with not a peep from XP.
As far as the drivers, etc., all of those can be downloaded from Dell's support website (click on Service & Support, choose "Downloads" and input your service tag number).
You might also try calling or emailing Dell support (include your service tag number) and ask about replacement disks -- it's worth a shot.
Thanks for the tips and suggestion. I'll give that a try.
