Not a good idea XP on a machine that old. You will need lots more RAM and not sure if you can get all the necessary drivers. Recommend you go no better than 98SE - even then, you should look for 128 MB min ideally 256. HD - you could probably get away with 4.3 GB but this assumes that you never go beyond internet usage. However, rather than Ebay, where you will double the price in postage costs, why not get along to a Computer show and pick up something there.
