Good job on the mod, as my hands are too shakey naturally to do that kind of mod.

You should post some pictures up if you have the time and a mod guide for your paticular PowerBook, so others will not make the same blunders while modding. I bet a lot of people who have the hands to sauder that close would like to know which angles to approach the best and hand wrests.

As for your English, it's just fine.

And as a final note, are you planning any additional mods to your PowerBook?
