The only OEM or 32-but version I can find is the "for system builders" version which says it cannot be transfered to another computer. What exactly does this mean? If I change my mobo or processor will it become useless?

For further info,
view the CF poll that discusses OEM vs. Retail. The consensus on this forum suggests that OEM is far better than retail. Normally, I would disagree. However, in your situation, I think you should choose between 32 and 64 bit, and not concern yourself w/ significant hardware changes that could affect your product key.
Read the license agreement carefully. Microsoft only requires that you purchase a piece of hardware W/ the software, and refuses to offer customer support for OEM license holders'. Product support is offered here, 10,000 other forums, and on the MS website. Don't let the lack of "technical support" prevent you from saving a few bucks.
Finally, the most you would have to do, it seems, is call MS if you upgrade your mobo from the current build. You would most likely have to re-install Windows in order for the license to transfer - not to mention a successful install - to take place. Unfortunately, simply popping in your HD into the upgraded mobo will not allow you to successfully boot your old installation.
As far as I know, changing the CPU will not trigger a reactivation.
Good luck, Netskimmer.
