So I've acquired an old PowerBook G4 867mhz recently, and it's in need of some love. I've cleaned it as best I could (it was very dirty when it arrived) I've ordered the highest upgrades I could find (1gb ram and a 320gb hdd) I'm going to also need to replace the battery and most likely the power adapter. That being said, the bottom case is in pretty poor condition. The top case and LCD back is also sort of scratched up. I'm wondering where the best source would be to acquire the replacement parts. I'd rather not use eBay because I'm unable to use my paypal account. Any ideas?
