Thanks for the tips. The dings are pretty shallow so I'll go ahead with the woodputty. I'll check out the bondo threads, because I'll probably want to fill the old controller holes before drilling the new ones.
Speaking of threads, can you folks point me to some good ones on removing the side art and putting in some speakers? I've got an old PC sound system with a busted speaker - I'm thinking of salvaging the amp and just find some car speakers to add to the mix - that should work, right?
