- Speakers and an audio amp. With a RasPi in there, it would be nice to
  also have audio output. I could either design the amplifier myself or
  use a bit more of an elegant solution inline. I'd like to control the
  volume with the knob originally used to control the display
  brightness.

- Raspberry Pi 3. I currently have a RasPi 2, which is fine, but I'd
  love to put a 3 in there if I could. It would be more powerful and
  also have wireless out of the box.

- A cheeseburger. I'm freaking hungry (and an American).

- A USB hub to mount towards the rear of the machine so that I don't
have to open the case just to access the Pi's USB.

- A boyfriend (but I can't buy that)
