It would be useful to note here that if you want to insert the little blue triangular iFixit opening picks into the right side along the edge, there isn't actually a gap as the directions say, at least not on newer Decks. You'll be making the initial gap using the pick. Brace it on something because you will need to use enough downward force that you're flexing the pick a bit and it'll probably be digging into the skin of a bare hand. With enough force suddenly it will make a click and go in just a bit, and then you're in business.

I would recommend against using Arctic Silver on the PowerBook due to the long curing process. Arctic Cooling MX-4 does just as well without the need to cure, and also lasts longer. I've been using that on old PowerBook maintenance re-applications and it does very well.

You're welcome! I was the one who added the spudger tips, as I had a devil of a time making the DVD drive clips snap back into place without one when I followed this guide.
