u never know, it might be a good sample of the celery he has, try overclocking it to 133mhz fsb (its just a neutered p3) for some (scratches head) 1.7ghz fun, then id chuck the p3 in the other machine and keep the pcelery. It might not quite reach that high, but will cert overclock between 100mhz and 133mhz giving you between 1.3 and 1.7.

Have some fun with trying the overclock, its all old stuff now and can be replaced for pennies on fleabay if u get it royally rong. (not likely)
