The most efficient CPU are still the VIA ones... Low power, very low 
heat, very low noise.
There are lots of EPIA mobos (Mini-ITX for factor) with fanless CPUs 
around. With these, you get only one PCI slot, but everything is 
integrated on the motherboard.
Using a good laptop-like power block (efficient and fanless), you can 
have a really silent setup (one slow fan for the whole system).

Drop noise:
* suspend the disk drive with rubber bands
* carefully design the air path inside the case
