i have a mentally disabled friend with not much money and he wants a pc for gaming. he knows he cant afford a top of the line pc and would happily settle for something much cheaper as long as it gets him from point a to point b. he needs a prebuilt system. he doesnt have an lcd monitor eaither so he needs that too. keep in mind, what you may think is old and obsolete would make him quite happy. what would you recommend?
