i have a pentium 3 which has been turned on 24/7 for probably the past 5 years with very few exceptions. every 6 months or so I blow out the dust that acures from sitting on the floor in my living room. it serves as my media center (hooked to my stereo, serves as firewall for my internet connection, etc). you should have no problem leaving your computer on all night. you will want to make sure it's well ventalated. don't put it in a closed cabinet. other than that youshouldn't have a problem.
