Think long and hard as to why you want to buy a computer. Do you want to buy a computer to get on the Internet or do you want to run a specific software application? Do you want to buy a computer just to play games? Then you might be better off buying a game console like a Sony PlayStation 2. It makes a lot of difference for which purpose you buy a computer, as to what hardware configuration you should look for and the price you have to pay for it.
