Oh I will be having lights and LED fans. Old PSU's and the PC Custom Lighting Kits are so cheap now it would be silly not to really.
I'm thinking more along the lines of making the actual frame a different colour once its finished.
It would be nice to have a Red outer Frame and Black Axis Frames without having to rely on Plastic Printed Parts adding the colour.
Or Orange and Black like the Mk2.
Out of the box thinking is easier when you never fitted in the box to begin with.
