I've talked a lot about my experience ripping open my old Dell Inspiron laptop. Here are some pictures.

Here's a picture of the laptop with the palmrest assembly removed:

Notice the battery and floppy disk have already been removed, which are the two empty bays at the bottom left and right of the picture.

On the left is the PCMCIA slot. On the right is the laptop security mechanism, to which a cable can be attached so noone steals your laptop off your office desk. Just to the left of the security mechanism, taking up most of the right side of the motherboard, is a complex looking heat redistribution system.
