I took some photos of the Dreamcast today while dismantling it. I'm sure there are plenty already out there, but here are some that I took:
http://senkbeil.no-ip.org/tmp/photos/These aren't resized from my camera and I'm not sure if I can resize images with BB tags; so, I'm only going to show one here.
First one:

Resized versions of these will be put up on my site's Dreamcast section once I have time to redo the design. And, no, I didn't have any intention to keep a working GD-ROM reader, which is why I didn't care about taking it apart (although everything could still be put back together). If it broke in the process, that's okay to me. Got this Dreamcast for $15 and wanted to document the internals. Plus, the whole thing reeks of smoke, which I'm not fond of.
[EDIT]
Whoops, used the local address instead of the public reroute since I'm used to accessing my site from the same network.

Also, provided a sample shrunk to a much, much, MUCH smaller size!
