I am a cheapskate and have bought many used computers over the years.  I knew as soon as I took it out of the box that it was not what I wanted to deal with.  It still had the previous owner's info--documents, pictures, ect.  The USB ports were difficult to use, like they were warped.  It came with an internet adapter, not the built in wireless that I wanted.  I sent it back within a few days, and I am the type of person that never sends anything back or returns stuff to stores.  I just knew it was not for me.  I decided to not waste my money and bought a new PC that arrived today.
