Hmm, i wonder - has anyone around here seen these? Other than that, i know there's 5mm ones, but meh. I plot on throwing three/four into every fan in serial, then connect them to a front mounted set of rheostats, as so to be able to adjust the 4 (maybe 6, if i choose to add 80s) fans colors - 120 - Side Panel, PSU, Rear fan 80 - NB, right panel, left panel.

So it is. Anyone care to elaborate what rheo i can use to bring either 12v down to 0v, or to run the wires in parallel, and start them all at 3.3v, then bring them down to 0? I plot to run four rheos at the case front, along with a demo LED up front to show the color of all the other lights.
