Really nice looking build G_Dubs. I was quite pleased with the way mine looked until I saw yours.
I have wondered how people hid the fly wires from the fans, I guess you just tape them around the outside of the fan itself.
I have managed to reroute that stray 8-pin lead around behind the motherboard now which make a big difference.
My biggest gripe is the power leads to the graphics card. Not sure what to do abut these.
Also there's the USB 3 port just above the PSU, that cable looks ugly too,
