System is lightning fast. Boots in 15 seconds. If it would have come in the original packaging i would have not known it was used. It was that clean. It came as advertised. What was not clear was the DVD. It arrived with a DVDRW. Love the layout of this computer. Everything is easily accessible. Expansion will be a breeze. Bought a 2 pack of 4K Ultra HD Display Port to HDMI adapters to hook up 2 additional monitors. Super cool. i am a video fanatic. The intel 4600 integrated graphics card with 2G of shared memory will handle all your streaming and DVD needs. It has 4 Expansion slots for a dedicated card if you need more for gaming. I am not a gamer so I don't know how the 4600 will handle them. But this system handles all my needs lighting fast. Could not be happier. Bought mine from Quality Recertified. Great job gang. They even did all the Windows updates before shipping. So with the included Network dongle that hooked up instantly.... this thing was screaming right out of the box. Get yours while they last. But not before I go back for seconds. My wife wants one too! Heres to 2021!Came back for seconds and Quality Recertified  did it again! Better than expected delivery time and Received another clean as a whistle desktop. My wife is very happy! Happy wife happy life....or so the saying goes. Everybody's happy.....you can be too! Quality Recertified will see to it. Thanks again gang!
