The 1st computer stopped in 2 months. they replaced it. Then had trouble with one of the screens and they told me to buy another vga connector, then it stopped working completely  in about 8 months. They said take it to a repair shop which I did and it needed a new power supply to the tune of $180 including labor. Definatly not worth the money. ITs not a good refurbished product andAmazon sholdnt be selling this item.
