With readily-available, cheap fans and a regular PC case, a little duct 
tape, some creativity and a little bit of rewiring, you can get a PC very 
very quiet.  I record quiet acoustic guitars all the time next to my PC 
(1.4GHz AMD with three hard drives).  HD spindle noise is the only audible 
noise.  The fans are not audible even with 60dB of gain and an omni 
condenser mic less than 10 feet away.

The key is to rework the air flow so the only exhaust fan is in the power 
supply, air inlet is at the opposite corner of the box, run all the fans on 
7V (gotta rewire, and open the p/s and disconnect the fan, run the wire out 
of the p/s and power the p/s fan from the mobo).  Use sleeve bearing fans 
that are very quiet.  Grommet-mount the hard disks or suspend them with 
ponytail elastics & zip-ties in the 5.25" bays to decouple the vibration 
noise.  Then once the machine is together, find all air leaks and seal them 
with duct tape (except the CD drive, intentional air inlet...).
