RGB computer lighting. It's the latest trend these days.
I've bought into that trend.
Through Corsair, I've obtained an RBG keyboard, mouse and mouse pad. My goal is to get a new case, and shove a multitude of glowing RBG goodness filled fans in there, so I no longer need to turn on the office light.
And maybe a couple of RBG LED strips for the front of the monitor.
You can never have too much blinky bling...
