I'll post this here even though it's not a DIY mod like those awesome ones you posted, rgamer.
A modular effort from Razer, http://www.razerzone.com/christine
They seem to be saying all the connections are PCIe but that surely couldn't work for the RAM. Even if you gave it 10 PCIe lanes the latency would be horrible. I like the idea of plugging all the components directly into the cooling loop though and it looks rather swanky.
Anyway, it's from Razer so it'll cost a fortune and I will never own one.
