Seems a shame to kill that for parts - it looks a lovely little machine. I'd love something like that - PPC or even colour-screen Mac laptops seem extremely hard to come by. Hopefully you'll put the 250 CPU and loose hinges on that one rather than scrapping it completely, as with an HD and Ram (pretty standard components presumably) you'd have another rather nice laptop, as long as the hinges are strong enough to hold it open.

Do you have the service manual for it, as that may or may not help you out?
