[Help] Opening the GBA SP

I'm planning on changing the shell of my GBA SP. It's scratched up quite badly on the top, and I've always felt I made the wrong choice buying a silver one so I'd like to change it to black. There's also a highly irritating piece of lint smack right in the middle of the screen that is highly visible, and I've been meaning to take it apart to remove it. I don't really want to do this without prior knowledge, so I've been scouring the net hoping to find an odd tutorial or a gallery that will warn me of the secret contraptions that will destroy the CPU if it's opened. However, I've spent the past 2 hours looking and haven't found anything, you disappoint me, intarnet. >=0

If you know of a site which has information on GBA SP disassembly, or if you've done it yourself and have some experience to share, then please post.

Jam it back in, in the dark.
