Yeah, it took 3 days to get it right for me. A few careless mistakes where the video went a little fast. I'm just deciding if I'm going to keep it on here before I put my OS X on it. Another thing too is if you download any of the Airport updates after the 10.5.6 update, you'll have to run the wifi fix again. I figured that out last night. I also found that moving the dock to the right side of the screen gives me considerably more working space, and only issues with a few site on having to pan left/right.
BTW, a little white apple logo out of an ipod box is perfectly proportioned for the top case of your machine.
