ok so im sure you guys have seen the article that explains how to make a rheo baybus that you cant overload, heres the link if you need it: http://www.bit-tech.net/article/32/ anyways, i think i understand it pretty well, but i need some help on understanding how the fans are actually plugged in. http://www.bit-tech.net/images/articles/80/image006.jpg i see that theres a + line going into the fans, but i dont see a -/grnd line going out. i plan on hooking up some male 3pin connectors for it and i cant figure that part out. thanks for your help in advance.
