I am very happy with my refurbished computer.I took it out of the box, plugged it in, and everything worked perfectly.I wanted a file-server for my home network and this unit had 4 USB 3.0 ports which is what I wanted.As a side note, Windows has a neat feature where you can just plug-in all your random USB/Firewire/internal drives, and it will add them all to a 'pool' which looks like a single drive. This is what I did, and my little HP Elite does this job just fine.I still can't believe the price, you couldn't come close to building this computer for the price I paid for the complete unit.
