I ordered a PC for a project.  Used, whatever, just be a fricking PC.  And this thing gave me no trouble, no activation heartache, nothing wrong with it; totally like new except that obviously  it's a bit older spec.  The machine came with detailed instructions for activating Windows whatever in case I needed to do it on a submarine or the Moon with no connectivity, but I didn't need any of that.  It just works.  And true to the seller's claims (actually in excess of claims), there are absolutely ZERO marks, no scratches, blemishes, dead pixels, odd noises -- this thing is the RIGHT ANSWER.I got a business PC from a few years ago in NEW condition for under $400.  Perfect.
