If you *really* hate noise, and want a total silent config, then you need either watercooling, or fanless solutions.
- total watercooling: can be expensive, but very efficient. You can use a rad big enough (and design accordingly) to be passively cooled, i.e. it will need no fan. You will have to mount it outside the case.
- fanless components: Zalman make CPU, GPU and NB fanless heatsinks, that work quite well. Their latest GPU double-heatsink (connected with a heatpipe) looks great.
Since you are in USA you should check out TK Power PSU (available at silicon acoustics, for example), it's fanless...
Do not forget to suspend / insulate your HDD.
