In my experience you can't have quiet and performance if you want low temperatures. I have a B3 Xeon clocked at 3.4Ghz with a passive Thermalright HR-01 on it. It hits 85C under load, but it's totally stable. It's also totally silent because it has no fan.
A good high-flow water system (like the one you have specified) will keep an overclocked B3 CPU running at about 45C at idle/75C under load with no fans running at all, or about 35 idle/60 load with 2 7V Yate Loon fans, or about 32 idle/55 load with 2 12V Yate Loon fans. I think you have to determine what trade-off you are prepared to accept between noise and performance before you can really specify a system.
The other point I would raise is this one of using massively powerful pumps in very short loops. I only use the 18W Ultra when I'm running a big passive loop, everywhere else I use the 10W Pro or the Laing D5 type pump running at the minimum setting. Moving water sloshing about is very noisy, as is the sound of bubbles passing through pumps and reservoirs (cavitation) so I would suggest going for a less oomphy pump on your system. Maybe even something like the D-Tek DB1. Excess pump capacity in a water-cooling loop is a bad thing in my opinion. If you buy quality kit, you'll not lose much when you sell it on to upgrade later.
Like CyZMyAssBaby, I would ditch the DD reservoir for a Swiftech MicroRes - it's very flexible in terms of mounting options, and it's very well sorted in terms of reducing bubbles and cavitation. I would suggest you get it re-tapped for G1/4 on all three ports though as it allows the fitment of a fillport or a proper brass allen-bolt in the filler, which is just soft plastic and always gets chewed up. The plastic G3/8 barbs supplied are also great until you have to get the tubing off, at which point they are a massive liability.
I also wouldn't rule out units like the Zalman Reserator 2, the Preytek Serenity, CapeCora or the Alphacool 120.9 radiators which sit on the outside of the case, but are genuinely silent. If you can control the room temperature these are silent, and will cool your CPU very nicely indeed.
