I was a little leery about getting a refurbished PC, but I am very pleased with this unit.  The system arrived boxed and wrapped well.  Minor issue is that it was missing one power cable for a monitor, and one display port to DVI cable.  I called the support number provided by the card in the box told them about the problem and they said they would send me new cables.  Even without being able to use the second monitor I booted the machine and finished the Windows 10 install without a problem.  The cables arrived two business days later as promised and worked fine.  I have not had any issues with the machine since then.  I would purchase from this seller again.
