I am using the PW-200-M DC-DC psu in an EPIA-6000 non-Myth box at the
moment.  I was going to use it for my raid box, but it was not quite
powerful enough for that, though I hear other people have managed it.
The biggest pain I had was in finding a silent-ish brick that could
deliver 200W at 12V.  I do not know if its still a problem  finding
them, but what I finaly got was an Xbox 360 powersupply (203W) off of
ebay for $20.  It took little work to get things hooked up, but its
been working for the last year without incident.

If you want to know...

To connect the brick to the PW-200-M I went to Wal-Mart and bought a
Nyko Intercooler and to Radio Shack to get a Size L Coaxial DC Power
Connector.I took the socket out of the Intercooler and soldered the DC
power connector to the appropriate (I don't remember) connectors that
I found with a volt meter.  If you are familiar with meter then it
will be easy enough to find out which ports have power running through
them.  I epoxied the socket into a hole I made in the back of my case.
 Plugged the size L connector into the PW-200-M, plugged the brick
into the socket from the Nyko, and voila, a live motherboard.
