Product arrived two days early (thanks, FedEx!) in perfect condition.  One minor scratch on the case along with some paint wear on one edge were the only indicators this wasn't a new computer, but the case itself was sparkling clean. I checked inside and discovered that it was also very clean and had apparently been blown out. Startup and boot were very uneventful and quick. I found that I had been shipped an i5-4590 in lieu of the i5-4570 I had ordered, so that was a nice surprise. Diagnostics reported everything was in perfect order, and the case sticker noted the OS was Win10 for Refurbished PC's. From a functional standpoint, this machined behaved as if it were a brand new computer from Dell. Scandisk reported no errors on the disk, and a third-party diagnostics program comes with a shortcut on the desktop. Network connection via Cat 5 cable was effortless with excellent connectivity speed to my local ISP. I installed software and ran the computer for a couple of days with no problems whatsoever. I've purchased refurbished units before and they arrived in a well-used box with paper as packaging material. For my mosedt needs, this computer will give me many years of use.
