I've set up a few systems with a number of different Swiftech blocks, emphasis has been on quiet. If you are cooling only a CPU, don't care about overclocking (to temps just under max allowable are OK) then you'll be fine with a 6000, 1046, 3/8" tubing and a BIP.
If you'd like better performance, swap out the BIP for a BIP2 or a 6"x6" heater core with shroud.
Better than that, go with a 1048 or a HPPS (12V variant of the 1046, quieter than the 1046, seems to pump 1046 volumes at 0 head but is more like the 1048 at higher resistance).
All of this assumes that you're running very quiet fans, with airflows to match.
Also remember that you have to be careful to avoid water flow resistance (no right angles if you can avoid it, for instance) and air flow resistance (rounded cables, wires tied out of air path, non-restrictive grilles, etc.).
I've tried swapping 3/8" ID tubing for 1/2" ID (same system, wb left in place to avoid possible variation from a re-mount) and have seen, well...
no temp improvement (using the crude measuring stick of MBM). Given that 1/2" tubing is going to have a larger OD, and so cause more airflow disruption, maybe 3/8" is better for low-noise. I've no way to measure this accurately, so please just regard this as "thinking out loud".
