The Sega CD was worth it for Sonic CD, but IMHO that was about it, haha. I have a Sega CDX. I don't think I'd be able to fit much into it if I tried this, not that I'd ever take it apart anyway... too near and dear. :)

It ran Prime for about 10 minutes with no problems but I didn't thoroughly test it. Wasn't supposed to be a 24/7 OC anyway, just an experiment.

Check out those core temps!
How much higher have you guys taken your i5-750s?
