Has anyone done a mod to the DG-87 arrow buttons? I'm going to go PWM with a fan controller for the case fans that would have been controlled by the giant buttons on the case.
 
Just wondering if anyone has modded their case buttons to do something cool.
 
I'm not super creative but I was thinking about maybe making the buttons change mouse profiles/dpi settings or maybe cycle RGB color schemes or maybe work windows volume or something useful instead of trying to manually adjust my fan speeds.
