If you could you could get 2 280 radiators in this case it would be all you would need, one at the front and one up top, they are very close area wise to a 360 radiator. Depth (thickness) is not a big factor, frontal area is, the 280s are a great improvement over a 240.

2 of them give a lot of cooling, but a good pump is needed for 3 blocks, something with around 1.5 gpm is nice, no bleading problems that way..

The more radiators-the quieter or higher overclock you'll be able to achieve. You can have 80 radiators if you really wanted :lol:.
You can't get below ambient unless you were to invest into a Peltier Build.
You can get a kit like this one: XSPC Copper Raystorm AX360 Extreme Intel CPU Water Cooling Kit w/ Twin D5
And add the GPU's to the loop.
Using Noctua or Cougar, Corsair or whatever fans you prefer (Higher Static Pressure for Push, higher CFM for pull).
The Order of the loop will only affect Temperature by 1 or 2*C. But prefer CPU-Radiator-GPU or CPU-GPU Radiator then reservoir.

The question is, how quiet do you want your pc? Personally I don't mind fan noise as long as it doesn't get picked up by my headset. If you share that view then, you do NOT need 2 radiators if you can fit a black ice gtx extreme 360. I am currently cooling TRI sli gtx 480's overclocked to 900/2200 @ 1.15 AND a delided 3770k overclocked to 4.6ghz. I use 4 3000rpm ultra kaze and 2 sickle flow in push pull and my temps are terrific! Max temps hit on gpu's during benchmarking was 55 degrees and CPU stayed under 65!! (before you comment the 3770k is safe up to 105). I use a D5 Laing pump, koolance 380i cpu block and 3 koolance vid-nx480 gpu blocks. Tubing is 1/2" ID and 5/8" OD (steel anti kink coils REALLY work).
The radiator is amazing! Twice as thick as standard radiators and fpi is extremely high. I fit everything in the Nvidia edition HAF X case with a touch of modding. The price I saved in not needing extra compression fittings was worth the better radiator. So, if you don't mind fan noise, you only need one radiator for that whole setup.
