This unit was exactly what they said it would be.  It came in a box with custom form-fitted bubble wrap protecting the contents.  The keyboard and mouse are very cheap but that's not what I was buying.  There was also a small WiFi N USB dongle plugged in the back - no capability for an antenna but again I plan to use the Ethernet port so that's no big deal for me. The system unit itself was extraordinarily clean - no dust and everything inside looked like it had been polished.  The only thing that made it look used (aside from no plastic protector sheet I could peel off on the front) was there was a slight ding in the trim plastic in one front corner.The system was packaged with a large "STOP - Do this first!" sheet that had a clear pictorial walk-through for setting it up,  finding the OS activation code, and steps needed to activate.  The system is pretty slow getting through POST on initial power up but once up and running it's very zippy (and will be zippier when I replace the slow mechanical hard drive with an SSD).  Also it's whisper quiet (I actually checked to make sure the fans were running).  Came with OEM Windows 10 Pro installed with an official Microsoft activation code sticker (good thing I have a magnifying glass) on the case.  It also had a large card from the seller with their support contact information and the seller has sent pre- and post-arrival "is everything OK?" emails so at least the seller appears to be available if there are issues.There are a couple of downers but not worth a star IMHO:  There's a very slight stale cigarette smell when it's running.  I have a very small poorly ventilated office and can barely smell it but it's there;  I figure that'll go away pretty soon but where I intend to use it is open so it's no biggie.  It has standard VGA and DisplayPort but no HDMI for video out.  It's also missing two slot cover plates from the back.  Pretty much that's it.It's relatively small.  Very zippy.  For the money it's a pretty durned good deal!
