I just wanted to add a few things that people should know if they intend to do this mod.
I got a brand new macbook in may 2007. Its a 2.16Ghz machine. I decided to do this mod.
Other people have mentioned, that when removing the screen assemby a magnet on the left hand side of the screen is not held in by anything, and so can be fiddly to get it to sit how it orginally was before removing the screen assembly. Others have also mentioned that the screws are quite small and soft, so it requires time and a very small screwdriver.
Three things I would like to add to this body of knowledge are as follows:-
a) when removing the thin plastic bezel that surrounds the screen it is attached to the screen assembly beneath by plastic clips. These plastic clips are small grey clips that hold the bexel and then themselves clip into the metal screen assembly. If your macbook is anything like mine, it doesn't matter how carefully you try and unclip the screen bezel, the grey clips pop out and unclip as well. This means once you have removed the screen bezel, you have about 16 small grey clips you have to try and carefully clip back into the screen assembly. This is diffuclt to do without mangling them.
b) I found that once I had removed the bezel and then clipped it completely back on after the mod, it seemed to not sit as flat as before, especially in the bottom corners of the screen, it flaired out a very small amount. It would be a good idea to have some double sided 3M tape handy to apply in this area.
c) once you have opened the screen up, you can then cut away the first piece of film behind the logo. But this does not mean that after this the logo will be completely transparent, as it has a backing on itself that is opqaue. This can be good as the logo will seem to be a off-white when not lit from behind, but once the macbook is on, it illumniates the new colour you have added. But depending on the colour it can end up that you have a much less bright light, and only a tint of your colour added.
My thoughts after doing the mod is that you really have to want to stand out to both with this, and the disadvantages of opening up you macbook, could quite possibly out-weigh the wow factor you get from your new mod. If you deem yourself a bit clumsy or impatient don't do this mod. But now you know all the possible pitfalls.
Sorry about the long post.
