Dress up in old tattered clothes, go to a street corner in town, place an upside down hat in front of you, display some sort of talent (Something musical, like an instrument, or maybe dancing.), make money, invest in lottery tickets, win big, buy 10000 of those computers, live in a house constructed entirely of them, pay for tours inside, start your own business with the money profited from that, create a board of directors, become mentally unstable, have them vote you off the board, murder them in a blind rage, face criminal charges of first degree murder, be tried as an adult, go to jail for 50 years, come out with your business having collapsed and your home repossessed, then mow your parents lawns for a year or so and borrow the balance remaining from them and arrange to work it off. Then you'll have the computer of your dreams. :D
