Someone just replaced the black keyboard with a keyboard from the beige version.
As for the wood grain, I haven't a clue. Always loved the brushed aluminum look...
The speaker grille is most likely for heat dissipation - the power supply is right under there, and generates a fair amount of heat - especially the older one that came with the black&silver TIs. A later model runs much cooler, and only has two pins on the input instead of the usual four.
But what is that protruding from the I/O port on the right side of the computer? Can you get a better picture of that?
