Nope, all dependant on the motherboard & GPU, it's looking pretty certain that the GPU will be the EVGA GTX 580 Watercooled version, which doesn't seem to have very much of any particular colour. At the moment my current thinking is wait until the GPU comes out (supposed to be the end of the month) and see how I feel then, if I can wait for Sandy Bridge & CORE i7s then I will, otherwise its ASUS Rampage III and i7 950. My preference was blue coolant but it's more likely that hardware will force me to go red.
To be honest the hardest decision is which colour scheme to go with, one of my reasons for getting the Gentle Typhoons (fans) was that I could paint them matt black and not have a 'showy' case full of bling-bling fans with loads of LEDS, I prefer the coolant and tubing to do the showing off and let everything else fade into the background, I think it will give it a much more clean look.
