My girlfriend has a PII - 266Mhz CPU in an old dell computer. She has 192MB of EDO Ram. (I think that the right name....anyways it's the really old stuff, no SDRAM) It has the stock HSF and I was wondering if it would be safe heat wise to overclock this. I can change the FSB from 66 to 100. The case is not a tower...it's one of the flat desktop ones.
