I have a 1.25ghz Mac mini with a 40gb hard drive... well i ripped my baby open and installed a 60gb 7200 rpm drive... well the performance is noticeably better, i am kinda afraid that the mini can't handle the 7200 rpm drive and might get too warm.... i'm not sure if i notice the fans more in the mini because i only had the computer for like a week before i upgraded the hd and i got the mini like a week or 2 after they were announced... so any thoughts? should i worry at all? i haven't had any problems at all just the fans kick on when i'm encoding dvds and stuff like that....
