Depending on which bus we are using, we should connect the keyboard differently, as we have seen recommendations on the Corsair forums:

The new Cherry MX RGB RED switches allow RGB Single Key Illumination with Cherry Refract Technology. This technology means that a computer-calculated lens-set is diverging the lighting from the SMD-LED on the circuit board loss-free to the key cap; also, we are dealing with a linear switch, which has a distance to actuation point of 2mm and an operating force of about 45cN. The housing base is made of translucent plastic polymer and has a recess for the SMD LED on the circuit board:

Thanks to the aluminum base, the LED light for each switch creates a very interesting effect:

After connecting the keyboard for the first time, In the default mode all keys will light up red except WASD and directional keys which will pulsate white:

If we look on the side, the translucent plastic body of the Cherry MX RGB Red switches looks awesome:
