I was hoping to add some more flare to my PC but my motherboard is a little bit older and does not have RGB headers, only a bunch of empty fan headers. From the information I gathered the Lian Li cables have to be connected to ARGB 3-pin headers. I already have commander pro and it's pretty much full except for the 2 USB headers. Is there anywhere I can connect these or am I just out of luck with adding these cables to my machine?
