As a University student, I had dual Athlon XPs on a Tyan board. It was a lot of money for me back then, and the power supply melted to the board (not the power supply's fault either. I soldered on a new ATX connector and the 2nd power supply also melted to the board). If I couldn't use those processors in any other machines except a Tyan, I would be insanely pissed off.
