I am in the US Army at Fort Gordon and have access to computers, but only for the internet. No peripherals, just a screen, keyboard and mouse, and money insert / credit card insert. What I'm looking for is a, in a sense, cigar box computer. Power isn't a need much, just something to get on the internet with wirelessly (big one, no land lines), USB Ports, decent HDD (100 to 500 GB), and analog output [video, audio] (yellow, red, white). Windows XP Pro compatible too. Thank you.
