I have some questions that perhaps Bruce can answer if he's not too busy.
-Why the strong suggestion to use 1/2" and 7/16" ID tubing? It seems unusual.
-Someone also recently suggested that blocks similar to this often have clearance issues with popular ramsinks, namely the OCZ copper BGA. Can we have confirmation that this isn't an issue?

RVWinkle Jaydee and MaxSaleen are absolutely right... You can not treat high end GPUs releasing 100W + heat any different than high end CPUs anymore... Just like the CPU block designs, the GPU block designs must evolve accordingly...
As for the suggestion to use 7/16"ID and 1/2"ID tubing with high flow 1/2" barbs, some folks e-mailed us asking if it's OK to use 7/16"ID tubing instead of 1/2"ID with 1/2"OD barbs, and the answer is absolutely OK to use 7/16"ID tubing with 1/2" barbs. And that's the reason why I put Cooltechnica recommends 7/16"ID and 1/2"ID tubing with 1/2" barbed fittings...
I'm getting some high flow 3/8" barbs with large inside diameter made as well...
FYI I personally use 3/8"ID tubing over 1/2"barbed fittings, and use 1/2"ID tubing only for Tee F&B, or between the outlet of a reservoir and the pump. You can simply heat up the ends of 3/8"ID tubing and stretch it over larger 1/2"OD barbs...
