Took it out of the box & set it up with ease.  Only issue was keyboard did not work nor did the wifi dongle.  This computer is just a few feet from my router so a cable took care of the wifi issue & my old keyboard still works great.  Amazon CS made good on those 2 issues with one phone call.  It is blinding fast & speed was the biggest complaint with the old computer until the hard disk crashed.  I have never had an issue with anything purchased from Amazon that if there was an issue they didn't do right by me.
