Upon receiving unit wasn't even able to finish initial setup without receiving random error message and fan bearings were making awful racket. On second boot unit would not see hard drive. Provided wireless card is 2.4Ghz only and will not connect to my network.There is no way this "renewed" unit was ever tested for functionality or even looked at by anyone who had a clue as to what they were doing. Avoid this company at all costs or prepare to fix it Yourself.
