I LOVE
I've always been a fan of roccat:
Sober hardware, always functional, reliable. Combined with my roccat kone aimo and the roccat mouse/keyboard mat, you have a nice gaming station with the little AIMO technology that synchronises all the lighting according to your activity.
The only downside for the fussy: the switches aren't changeable, and they're not necessarily discreet, but there are worse things.
