To integrate the ion motherboard into a G19 keyboard, sort of like how a commodore 64 was an all in one keyboard sort of design. The motherboard would be on the bottom, the keyboard would need a new housing on the bottom in order to fit it, but use the top half/design of the G19 keyboard on top. On the right, you would have a slimline optical drive, and integrated into it would be a small "subwoofer" sort of speaker on the left side , and two smaller satelites built into the top parts. The wrist support would be custom molded, with a nice gel or foam padding of some sort. The overall color theme would be black and green, like the nvidia colors.
Also, i was thinking about the ergonomic supports but forgot to put it in the image. Would definately need wrist support.
