This comes to us from Best Buy - likely a display unit. It was reset by their technicians, and there's a white piece of paper on the side of the machine that details what was done, who did it, whether it passed or not... etc. It has both a 1 TB hard drive as well as a 128GB SSD for better performance. Rest of the specs are in one of the pictures we posted. Monitor (19") / keyboard / mouse / speakers /headset included with this unit at this price. Exact brand of accessories may not be what's in the picture, depending upon what's available at the time of the sale.
