Do you have an old xbox that you bought years ago and played games on it for all of about 6 weeks? wondering what to do with it? well you could turn it in to a Media Center. that is what I did with mine, not only that you can put a bigger Hard Disk in too.
I have my xbox running with a 250GB HDD, have an F: for Music, Movies, Pictures etc.... and then a G: that I can copy my games on to! saves me having to find the Games when I do decide to play on...
