Another few pieces of advice:
Enable AHCI. This alone can help tremendously with disk noise, as it enables NCQ, which allows for much more linear access for both reads/writes. This results in less "scratching" of the disc. (Less random movement of the r/w head, which is what 90% of the noise from a hdd is.)
Use a current generation hdd. Switching from a not so old 7200.8 Seagate up to a newer 7200.10, and then to a 7200.11 has netted me much quieter hdd access. Now the loudest thing in my case is the PSU fan.
nVidia needs to remember what a hard launch is and apply it to what's left of their motherboard chipset department. That is all.
