recently i dug up my tough-as-nails ipod mini. released in 2004, it uses a 4GB hard drive and has one of the popular wolfson dacs in it. is it worth replacing the 4gb hard drive with a 32gb compactflash card, and the battery with something newer/higher capacity? i'll bypass the internal amplifier and use a line out cable to feed it to my cmoy-based portable amplifier
are the costs of a CF card + a replacement battery low enough to make a modded ipod mini a hi-fi player?
