Can I move my Vista install to a new computer?

Hey,

I was wondering if it's possible to move my Vista 32-bit Home Premium install to a new build and install a 64-bit version on the one thats currently 32-bit home premium. I'm building a media server so the 32-bit OS should be fine for that, my other system is my real system which I used 32-bit OS in because there were a lot of driver issues then. Lots of these issues have been worked out and I would really like access to the extra RAM so I was wondering if this is possible. I heard somewhere that each copy of Vista locks itself to the mobo it's installed on but can't verify. I'd e-mail M$ about it but they make you pay $59 for support...how ridiculous is that????
