Seller sent this computer very quickly. Apple box was a little worn but the computer was properly packaged with the Styrofoam inserts and the mouse, keyboard and cord were in a separate box. Computer appeared to be brand new, I could not find any scuffs or defects. Setup was quick and easy, internal components showed up on MacOS  just as listed. Retina screen is amazing, programs and the internet look sharp. This was a replacement for my 2009 iMac 27-inch model that finally gave up the ghost. I don't notice the smaller screen size at all. WiFi connections to internet and printer via my router went without a hitch.One thing to be aware of. Upgrading ram memory cannot be done by the user as the screen and many internal components have to be removed to get to the ram tray. On the 27 inch iMac's the user can easily upgrade ram by removing the tray from the bottom of the unit. So I would be sure to order the 8 meg ram and 1 TB hard drive as a minimum.Overall, I am quite happy with this purchase.
