I needed an inexpensive tower while my new tower was out for repair.I'm sure the quality and experience varies a lot on a refurbished product but I'm 100% satisfied. It came shrink wrapped with tape stating that it was refurbished by Microsoft. It is $80 cheaper than the same spec HP from Best Buy. Everything worked perfectly right out of the box.  It has 10 USB ports. It has no extra software to clutter up the machine.On top of everything else this one had a one year warranty vs most refurbished had 90 days. The additional service plans are very inexpensive. Because my new tower failed I needed something fast and this was free one day shipping also.One of my better purchases for the type of item I was very skeptical of.It may not matter but this has rubber feet on the side of housing and I think is meant to sit horizontally. There are no vents in the side panels. It is a slim design.I think this is around a 2011 vintage machine but considering the price refurbished I think it's a good value.
