Windows on a Mac

Now I'm no idiot, but I am looking for a cheap way to run Xp or Vista on my macbook. My school (GO PSU!) offers both in builders version. Can this be used or do I really need the Basic full install.

It would be helpful if people who used Builder suite responded, but I'll take anything.
Thnx, Mac (no, that really is my name)

The System Builders edition will work just fine.

I have (OEM) system builders version of Vista on my iMac and it works fine. The only difference to the full edition (XP and Vista) is that you cannot transfer it to another machine afterwards, as the OEM version can only be used on the 1st machine that it is installed on.
