Which you you prefer? THe dark center of the light center? I'm leaning towards the dark center because it makes the board look narrower. The case will be of the old 1980s laptop style (a Gridcase 1520), but with a wood case to house the Raspberry Pi system. I also have a 7" (6." x 5") monitor and a USB keyboard. The initial idea was to Steampunk it up, but I think I'll try a mixture of the early 1900s with a sophisticated interior look. That's the plan at the moment.
