So I can't use the pwm or 12 volt module to wore up some PC case fans?

You can use PWM to control the speed, but power would need to come from a dedicated power supply. Too much current.

Well that's perfect knowledge! I'll order a second relay box then. I found some good USB ones that come with the USB wall wart that will work. In out of outlets so this will give me a bit more room for expansion down the road. Once the cash is available I'll order a box, and a expansion hub then.
