I needed a good PC in a hurry to replace one that quit working at a customer site.  Time was critical in making this decision.  I ordered this one only after chatting first to verify shipping method, 2D shipping cost, being assured it would ship "today", AND that it would arrive on the specific date.  It was delivered on time, and after carefully it inspecting inside and out, determined this item is exactly as described (and better) by the seller, BTG.The PC case is in good condition.  For a refurbished machine, the interior is completely clean with NO dirt or dust on fans or heatsinks.  VERY CLEAN.  The 4x2GB sticks of RAM are all matched and same brand, another big issue.  Booted into Windows 10 Pro normally, and verified it is already up-to-date.  It is pretty quick and works great!  Includes a USB keyboard & USB mouse and Power cord, so it was ready to go right out of the box!After 2 days of setting it up for the customer, "so far so good".  I will update, if needed, regarding longer-term issues like the status and performance of the 500GB Hard Disk Drive and Power Supply.
