This computer arrived with dead USB ports on the back.  Within a day I had dead ports on the front too.  The seller sent me a small refund to cover buying a USB expansion card, which i did.  Not very happy with that, but at least a solution.  Now, just six months later, the machine is completely dead.  May be the power supply, or worse.  Machine has always been a little glitchy anyway.  I'm a pretty disappointed user at this point.  We'll see if my extended warranty solves the dollar issue, but of course time is the real cost.  Would not recommend the seller.
