I was very hesitant to buy a refurbished computer but decided to give it a try due to the low price and buy the 3 year warranty in case of issues. The computer started up right out of the box and it only took me about 30 min to have everything up and running.  I've been using it for three days now and am very happy with it. The reason I didn't give it 5 stars is that my newer monitor has DVI or HDMI input and the computer only has VGA output to the monitor. I had to buy additional conversion adapters in order to get the monitor working.
