Updating this as I figured it out myself, and hopefully this may come in useful to somebody down the line who is searching for the same answer. Basically, the electronics are just held on to the front plate with some adhesive, and a couple of white plastic 'posts'. To get it off, I used a large (plastic) spudger to loosen around the edges, and then pulled the whole thing off from the top end. You want to make sure you are careful, as the electronics underneath are metal - and the PCB could snap if you are too rough. Replacing these in the new iPod is as simple as swapping them over. For some other tips that weren't obvious when I searched: 1. Restoring on a modern Mac is almost impossible, even with FireWire. The best option is to get a Windows XP Virtual Machine and restore using USB. The iPod will then work on your Macbook with USB fine. 2. If you upgrade your hard drive to an 80gb version, make sure you have the 30 or 40gb iPod, as the 20gb's back plate is not deep enough to accommodate the 80gb.
