I quickly designed this model, not to scale, of a Centurion Mini Computer to go along with my terminal clock/system module.
Inspired by Usagi Electric's computer.

I suggest printing the desk frame, side panels, top and drive handle in white, and the drive panels in blue filaments.

The front sides of the frame and top will need to be painted brown for that woodgrain look; the rest of the frame is good in black (or you can print the whole frame in black and then paint the front sides in brown, your choice).
