you're not really wrong, its just something MS doesn't want you to do since they would rather charge you 200 dollars for every new computer you make or buy. It's like how people who sell CDs would rather not have you rip MP3s off them even if you aren't pirating. Some will even take steps to make that impossible (by adding DRM to CDs, which some makers have done in the past such as with the fast and the furious soundtrack). Such changes were found to infringe on fair use rights.
Fair use rights are hard to get around, and just because Microsoft seeks to prevent you from doing something and puts it in the EULA does not mean they have the right to stop you from reusing a legally purchased OEM license. There is a reason they don't go after system builders or whoever else when they reuse OEM licenses, they know it would never hold up in court with any kind of consistency.
Frankly they're lucky when people buy even one OEM or retail copy of Vista/XP given how easy both OSes are to pirate, so suing people who use OEM copies more then once is shooting themselves in the foot and then some.
Also MS can't prove what system it was "made for" originally. They also make changing systems rather arbitrary (IE you can change the graphics card and its not a new system, but if you change the motherboard or processor then its magically a new system even though the upgrade costs were more or less identical). How are they going to prove that buying a new MB is different then buying a new graphics card? What line are they going to draw that is enforceable? That is where they are stepping on your fair use toes, they can SAY they have the right to decide how you can and cannot upgrade your own hardware, but they do not actually have any enforceable right there.
By saying "you can't install OEM software on a new machine" and "any change in component X even if component Y and Z stay the same constitutes a new machine" they are saying "if you upgrade your computer you must pay us a 200 dollar fee to do so" which doesn't just SEEM wrong, it IS wrong.
