To have a truly quiet system you need to have a fanless power supply. These DC-DC power supplies are exactly that. They are also made to be compact and form fitting with the top VIA mini-itx motherboards.
They run cool on only 12V current, so they are in turn also very efficient.

All the cases sold here have their own power supply, these are units sold separately for people who are interested in building their own custom mini-itx system. John used a PW-60 in his mini-itx case made from plexiglass and some gutter screen from a hardware store.
