In the service manula there is a specific section regarding Temperature Concerns. It points to a KB article on Apple’s site.
“Apple Notebooks: Operating Temperature.”

The whole top, including the keyboard is one piece. Neat.
The MacBook has a small Subwoofer, the Pro does not.
Magnets are everywhere. There’s one on the side for a sleep sensor, the one in the Magsafe connector, and two positioned on both sides of the integrated isight, to the far left and right corners. The magents used to keep the lid shut are huge. Ok, not freakishly huge, but about the size of 2 1/2 keys on a Macbook keyboard.
