I bought my Dell from a repair computer place. My Dell desktop I am using right now had been used at a school. It was wiped off all and was a bare bones. I bought it in 2013. It is a 2007. I am amazed myself it is still working. It will soon have to be replaced as it stops then starts up again...? Sometimes...(sometimes 4 times a days, sometimes runs for days) I use my Dell a lot and watch older movies or reruns of TV series. It has been a very good working machine. I have another Dell 2013 underneath this one I am writing about. Also used. It is a professional model too. Buying 2nd hand (for me is like buying a used car) Its proven already it will last and all the kinks have been worked out.
