So far I have had no issues with this computer.  I worked right out of the box.  Although I have only had a few months so far it has performed well.  It is primary used for music serving and web browsing, so it is not heavily used.  There is no obvious lag when running music, multiple web browsers and Microsoft office applications all at the same time, however given the spec, I would not recommend for gaming or something graphics intensive like photo editing or video production.  I was a little leery of purchasing Renewed, however so far my fears have been unrealized and I would recommend.
