No dice - I carefully reviewed every sticker on the case when I had the computer unplugged, and there's nothing coming even close to any of the stickers mentioned in the link you provided me. There is an SKU number on the same sticker as the serial number I gave you previously, but I don't think that's it either (if it actually is, feel free to shout at me for wasting so much of your time =) ).
In addition, this computer used to have a cover over the CD/DVD drive slots (it actually only shipped with a CD(-R?) drive, though), which may have had the model number on it, but that cover was removed at some point (probably by myself; feel free to shout even more now) and I have no idea what may have happened to it since then. However, this computer also has a floppy and ZIP drive, and the bottom of the front has a serial port (I think) and two USB ports (if any of that helps narrow the list at all). I'd take pictures and upload them for you if I could, but I have no way to do so. =(
