Buy new.  A waste of time setting it up then discovering that the monitor quality is horrible. The resolution is is blurry and cant be adjusted. This one came with duel monitors one had a green hue and the other a blue grey hue. I could not get them to be the same but even if I could they were so blurry and dull that it didn't matter/If I could live with a super low resolution screen ( and i can't) the computer is maddeningly slow. AND I have to PAY to ship it back. NO free return for this.  Again DONT WASTE YOUR MONEY.
