I don't have bitfenix LEDs but I have tested with cable mods RGB - thats what is in my video. But white matches up with my cable mods strip, so my suggestion is just test the bitfenix set.
If you remove the side panel, (metal side) you will see the RGB controller at the top front - there are two cables coming out of the bottom of the LED control unit, these two cables are capped with a plastic cover, but remove the caps and you have the 4 pin standard LED connectors, just plug in your LED strips and cycle through the modes.
Let me know if the colours all match up 100%, because currently the cable mods ones don't.
Red works fine
White works fine.
But some colours, like blue and green give different colours on the LED strip to the front panel Antec logo. That being said my unit I have test is also a pre-production sample, so final retail models maybe 100% spot on.
