This item shipped with paperwork in the box showing that it is refurbished by Dell, but when you call the phone number on the paperwork for support... Dell will not support it because it was not purchased directly from Dell.  Not only that, but there is a sticker on the bottom of each computer showing that it was refurbished by a third party.  The seller insists that their employees open and inspect each computer before shipping it out.One of my units shipped to me with a broken mouse, two of them were missing the WiFi antennas, and two of them had the CPU heat sinks and fans clogged with a thick layer of dust.  Some of the computers had 65w power supplies, some of them had 130w power supplies.  I'm not sure what size they are supposed to have.  These units were obviously not inspected or refurbished.The seller insists that the only returns which will be accepted are those where the computer is received DOA unless you want to pay a 15% restocking fee.  I had to properly clean each of these computers and replace the antennas myself.  It was cheaper than paying a 15% restocking fee.
