Picked one of these up to replace a desktop machine that is going bad in our office.  Unit I got was well packaged, looked like new (but for all the additional stickers on it).  One issue was the cover for the wifi antenna was missing.  Not a big deal.Started up just fine, Window's activated.  I did have to delete the video driver as it gave me the black screen after logging in (about the 5th time I started up).It is extremely quiet, and I am happy enough with it that I am buying a second one.
