I have seen some good (and bad) ideas from visiting the overclockers sites.

Some good pointers:

1)
try to mount anything that makes noise, with rubber washers between 
contact surfaces. For hard drives, it is a good idea to rig a wire or 
otherwise make sure the body of the drive stays grounded to the 
chassis.

2)
You can replace the fan in the power supply with a better model.
Be careful, if you have never poked around in a power supply before.

2a)
I've gotten a bunch of Panaflo fans. They are of high quality and 
move  a good amount of air without being too loud.

3)
On cheap PC stuff, I saw out the fan guards to reduce air turbulence.

4)
Have another unix machine? Learn how to run it diskless.
