Looking over that thread, the logic board doesn't seem that intimidating – my 586 ThinkPad was much worse to take apart.
The display puts the fear of God in me, though. I've never done anything with laptop displays. I've always just treated them as a single replaceable component. Add the fragile little tabs and you have one spooked Corgi.
The display has another issue, though. It was very hard to tell with the simple default PowerBook pattern, but the Nutmeg accent illustrates it very well. Unfortunately I can't capture a good photo of it with my phone. I feel like there was a name for this on old LCD panels. Basically, there are a bunch of light and dark places, and there is a discoloured patch on the right side. I mean yeah, it's a passive matrix from 1997, but I have other examples from this era that aren't quite this bad:
The discolouration on the bottom is phone noise, but the patch under the "Extra" disk is real.
