I can't tell, there are now cables apart from a dual (two stuck together) white cable and a thin (black/red - also stuck together) cable going somewhere in the approximate direction of the PSU... it is quite hard to remove to PSU to actually verify whether that white cable is going to the PSU for the case's structure restricts my disassembling methods unless I take out quite a few components first, and I also go on the internet with this system so disassembling and reassembling would be quite a pain.
