The unit came in a heavy-duty box with cushions at all 8 corners, so it was well protected. I wanted to add a second sound-card for my application (ham radio) so I needed to open the unit up to install it.  Everything was very clean inside - basically it looked new.  Outside, there were some minor scuffs on the front, but that is to be expected from a refurbished unit. Otherwise, the outside was also very clean.  A WiFi dongle (included) needs to be plugged into a USB port. The unit came right up and recognized the WiFI dongle.  There are very clear instructions on how to activate windows once you are powered up. A Windows CD was included, which is nice should something go wrong in the future requiring a software repair or re-install.  I received a follow-up email after delivery of the PC just to make sure everything was ok. The bottom line from my viewpoint is if you are looking for a quality PC and can live with a few scuffs, this is a good deal for the money.  If I had to list a negative, it would be that the price dropped from $329 to $299 the day after I ordered it - just my luck.
