Optiplex is Dell's corporate line, so this computer is well made.  The one I received was clean with very minor cosmetic damage (you have to search to find it).  It was originally sold in 2015.  The memory and drive were replaced.  The SSD model is MTG-480GB and was new according to SMART.  It has lots of USB ports.  Four front and six back.  Two on each side are high speed.  I replaced the Windows 10 with Linux and that was uneventful.  As others have noted, the machine has two DisplayPort ports.  It comes with one DisplayPort to HDMI adapter and the WiFi is also provided by an adapter.  I did not try the second.  I was looking at paying almost 3x this price for a new machine, so I'm very happy.
