First of all, note that the issue is with activation, not registration.
Registration is always completely optional; it's activation that's required.
If yours is a retail version of XP, there is no problem. You can change as
much hardware as you want and as often as you want. If you change enough
hardware you'll have to reactivate, but that should be no problem. And if
you change enough hardware within a 120-day period, you may have to activate
by voice call to an 800 number, but that should also be no problem--it's
normally quick and easy, usually under five minutes.
But if yours in a OEM version (for example, if it came with the computer)
there's another potential issue. The OEM license ties it permanently to the
first computer it's installed on and it may never be moved to another
computer (this is the main reason the OEM version is considerably less
expensive than a Full Retail version). Unfortunately the license does *not*
specify exactly what constitutes the same computer or a different one. You
say "rebuild my computer," but you don't specify exactly what you are
planning on changing. If yours is an OEM version, be aware that some people
consider changing the motherboard to make it a different computer, and if
you change it you may have a problem activating it.
