Arrived ahead of schedule and item was well packaged, however, upon opening the computer case I noticed that all 4 expansion slots were badly bent and the covers were missing.  When I tried to power the unit on it was DEAD.  NO POWER, NO functioning whatsoever.  Amazon "Certified" Refurbished is a load of crap.  I will NEVER purchase another Amazon Refurbished Item ever again.  Shame on you AMAZON.
