Hey guys i just got my 2.8 iMac couple days ago but i have a question Ive always left my computers on 24/7 but with the imac it just gets really hot in there with the display and all so i was wondering what do you guys do?? Do you guys leave your imacs on all the time or do you shut them off every night.. In the energy saver options i set the option to NEVER shut the computer off and NEVER put the hard disks to sleep. is this okay? or am i just too worried bout my new baby?
