This Dell Optiplex as sold by this SKYTECH USA LLC  was one of the best tech buys we've ever made, onamazon.com or elsewhere.  Buying a renewed or refurbished computer can be wiser than a new machine on the economy level  -- better components, faster, more powerful, better graphics.  This model provides everything we need for a desktop at a small price.  It is essentially brand new.  Also amazingly quiet.
