Computex has crazy mods for PCs and PC cases as far as the eye can see -- and that extends to keyboards, too.
RGB lighting was the big theme for components this year. If you wanted to control the LEDs in your case, case fans, keyboards, mice, hell even your cloth pad, there was a vendor offering a way.
A good idea of what the bog-standard RGB keyboard will look like -- a thin strip of lighting around the outside, and not much else within.
This was themed after the Captain America case mod that was also on display in Thermaltake's booth, from memory. If you haven't seen that, go check it out -- it's pretty special.
