Juggernaut, X58 Classified 4-way SLI system
 

There are still a few things I need to do (got some more cable management to take care of, need to install the four UV cold-cathodes for the tubing and fans, have to organise cutting a window in the side panel) plus a whole bunch of hardware gremlins , but I think I'm nearly there.

It's running two watercooling loops; one for the CPU and motherboard (running a single 360mm radiator), and one for the graphics cards (running dual 360mm radiators in parallel). The CPU loop runs at about 50°C idle and 60°C under load, the GPU loop at about 45°C idle and 55°C under load.
