Hey sure. I am delighted with how my project turned out, an old iPod is fantastic in the car, gym, while travelling without data allowance etc. I hadn't modded an iPod before this and it worked out ok.
Get an iPod classic, 5.5 gen if possiible (best DAC, for a nice warm sound)[1] A broken one, as long as it's not totally physically destroyed, is one way to go from ebay.
Get an offical iFlash device, I got the Quad with slots for up to 4 SD cards [2] Get some large capacity micro SD cards (x4 slots in the Quad, meaning several TBs are possible, for relatively cheap as the cards are getting cheaper by the day)
Upgrade the battery, if desired, optional but highly recommended [3]
Replace the front + back covers, clickwheel, screen as desired (pay attention to thin and thick back covers) [4]
For instructions on opening the case correctly, and replacing the parts, look on Youtube there's a bunch of decent videos explaining the process.
Look into installing rockbox[5], an open source firmware. It supports loads of audio formats and let's you escape the cluthes of itunes, to a much nicer application like Musicbee. WARNING for some reason, rockbox never worked correctly with my iPod 5.5 gen. I reinstalled several times, but songs would constantly skip while playing, even though they were fine on any other device. Therefore, I wiped rockbox again back to the Apple factory firmware, and everything works fine. I even figured out a way to sync Musicbee with the default Apple firmware.
If you really want to go nuts, you can install a bluetooth transmittor inside the newly freed up iPod case[6] I read though that the bluetooth has limited range inside the metal case, and it runs the battery down much more quickly.
