Just my own thoughts about your setup:
1) The copper G4, which is superior to the copper and silver Cascade blocks, will be available in 5-6 weeks from now. The silver G5 is not anticipated to happen until late October at which time I will invite orders and deposits to get a batch of silver on the way. I would expect around Christmas/January before those became a physical reality (other than the initial run of 5 which should happen by late October).
2) Those Delta 12cm 190CFM FFB fans, while bloody powerful (I have the 127mm equivalent which puts out 200CFM) have an incredible amount of bearing noise. The motors are very "meaty" as is required to drive those fans at those levels. Even when run at 5v they are annoyingly loud. I could not recommend any person who values their hearing and sanity to ever buy them for a system sitting within a few feet of them. For that radiator, which is essentially a BIX, I would say that perhaps a pair of Panaflo H1A's on the rheobus would be a better choice as they are very quiet when turned down to low speeds, unlike the Delta's, and still quite powerful when run at full chop. To me, they would be the saner choice as the Delta's at full speed might offer 1C lower water temps than the Panaflo's, but the Panaflo's won't drive you insane at lower voltages.
3) The DD Maze4 GPU block is good, but the Silverprop Nexus HL with the brass top offers a block made out of materials that doesn't require high levels of anti-corrosion agents.
4) NB block - Don't bother with it IMO. Find a decent copper CPU heatsink and cut it up and stick a small 5cm fan on it - it'll cool the NB as much as you need to, and sticking water-cooling on the NB would likely yield zero gains in comparison.
5) Pumps - fine - good choice.
6) A second radiator might lower water temps by 3-5C or so (depending on how fast you run the fans), which is something to keep in mind. Beyond that the temperature gains to be had are usually quite minimal and most people use larger radiators to trade off noise for performance.
