The Dell. 6520 computer was easy to set up. However, during use, the computer would randomly shut down several times during a session which was annoying. I noticed the computer was rather hot at the air vent area, so I assumed the computer shut down because of overheating. I returned the computer and was sent a replacement which, so far, appears to work well. I cannot say I would buy this computer again until I use it for awhile and operates properly.
