So in my trolling on ebay i happened to win a second gen ipod for next to nothing. great working condition they say, and the seller says i can return for a full refund if im unhappy, but thats beside the point.
obviously ill throw in a high capacity battery, but is it possible to get a 60GB Hard drive to fit inside? and work properly? ive seen 20GB, but alas, that is too small for me

I just filled up my 40GB 4th gen, and i dont really want to buy a video ipod just yet, plus this will be a fun little project.
any thoughts, ideas or recommendations?
