Great post! I'm actually using the same case and ordered the same keycaps (chocolatier) for my build, so don't mind if I say you have great taste 
Woot! Thanks.
The red plate was the best I could get for this as well... being behind the keys and darker, it kinda goes with all the brown.
I'm actually considering adding at least one or two LEDs as the firmware supports indicator lights for things like toggling the Windows key on/off, etc.
Just not 100% sure on the color (red or white).
I'm also not certain if:
1) I need extra parts (resistors etc) ... although I thought the GH60 already had surface-mounted components for this.
2) Which LEDs to get... what form factor/power etc...
Still need to read up.
