Don't argue with my on this, I have used two B&W G3 boards, a Sawtooth board and a Digital Audio board as my primary computer in an ATX case with ATX PSU.
I am currently using the Digital Audio with an Antec Neopower 650 Blue but I have used different PSUs with the previous boards. http://img131.imageshack.us/img131/3875/00000212yf5.jpg
Oh, and a side note, the Digital Audio boards are reasonably similar to the 2001 Quicksilver boards but not exactly. If you want "large drive support" you should look for a 2002 Quicksilver board. At one point I had the board numbers memorized(DA vs QS01 vs QS02) but they seem to have escaped me.
