This was refurbished and sold by Blair Technology Group.They have done an outstanding job of accurately describing what I was paying for, the condition of the unit itself, and when I needed an additional item installed in the PC to make it function for my needs, they were happy to accommodate me. (at a fair price)  It arrived in perfect condition, no scratches or dents.  I did check to see that the boards were still properly seated after shipment.I have had a few tech questions after everything was installed and running and they responded quickly with  useful information.I would;d not hesitate buying from them in the future.
