First time purchase of a refurbished desktop computer. Bad experience.  The program to activate Microsoft Win 10 Pro, did not work.  The screen freezes during initial input with a horizontal lines and stopped working.  I sent three website contacts to the vendor.  No response whatsoever.  The front panel had  cuts that could be seen from four feet away and two of the six front panel connection were broken.  The DVD disk did not open.  The vendor website had "Website is Coming Soon".  No detail on website.  No listing for hours of support or a phone number.  No help.  Returning item.
