These are some of worst condition refurbs that I have purchased - and I buy quite a few of them from various sellers on Amazon.  Very sloppy spray paint job on the cases - even some paint on the board inside the tower.  And there is a sketchy looking shortcut on the desktop that leads to a folder on the C drive called MININT, which is loaded with executable files.  A quick virus scan got rid of some of it, but I manually deleted the rest of the files.  Maybe its nothing, but I don't see a need for it...
