The quietest solution is cooling by water, but the quietest solution for
the best price is ripping off all fans from 30 to 96 mm and use 120 mm
fans. I've very good results with Enermax-12FAB-B running below 2000
rpm/s  (adjustable speed). Price is below 20,- Euro/pcs.

I advice you to remove CPU- and PSU-cooler and put one 120 mm fan into
the PSU to cool both. Put a second fan for the AGP/PCI-Slots (GFX with
heatpipe, no fan) directly mounted into the left door of the housing,
getting fresh air from outside.

Do so with a third or maybe fourth fan to cool your HDD-/DVD-devices.
It's important to get fresh air from outside as fans have to transport
the less air the cooler it is - and don't forget to have holes in the
top cover

Several big fans running at low rpm cause much less noise than one small
fan.
