Hi L.,
If you have trouble reactivating after a hardware
change you can use the telephone activation method.
Replacing the motherboard and CPU could be a problem,
if you're doing something other than replacing with
an identical part on failure.
Keeping just the 'same case', a non functional part,
probably doesn't count <g>.

OEM packages are intended for sale and use on the
computer as configured by the manufacturer.
==========
How much upgrade is allowed so the computer is still considered the original
computer?
If I change the harddrive and rest of the computer is the same, does
microsoft deny reactivation of OEM software? (harddrives do crash)
If I change motherboard and CPU but everthing else stays the same, is this
considered a new computer?
For me it still the same as I don't have another one. >>
