So I am planning on getting 3 HD140's and 3 HD120's. I will have several extra fan/lighting controllers that I won't use. Can I sacrifice one of those to do this?
Also I see where you solder the wires onto the Pro Micro, but where do those go to exactly from there? And how is the Pro Micro powered?
I have one of the Cablemod RGB lighting kits that has a sata to 5v could I use this somehow for this project. Specifically I have this kit
