Regarding the Deltatronic silent PSU...
There is some reference to this on http://groups.yahoo.com/group/Silent-PC/message/8050
where they claim it costs about EUR$300 ... Oopse... I see you are active over there too. Maybe you started the thread?
Unfortunately, the thing looks like it is rigged for European power.
The Bablefish translation of the page:
Strong exhaustless ATX Spezialnetzteil with large power reserves active PFC high efficiency high maximum stress particularly high maximum stream outstanding tension Konstanz large power reserves for Natural luftzirkulation supports extensions of all kinds high breakdown immunity design thermally secured, overload-proof, overvoltage-secured 360 the Watt power pack Silentium! SPS360A is an absolutely loudless and nevertheless very high performance power pack, which provides also with highest load peaks for outstanding tension Konstanz. Thus your computer is in the best possible way approximately crashes protected by instability of the current supply.
Hehe, the words "absolutely loudless" stand out.
Well, I am in your camp, stingpd. There ought to be a cheaper way to power a Silent PC. Still, the best retail deal I know of is the TK Power 300 from Orion http://www.orion-industries.com
which costs $144 + shipping. Have one glued to the roof of an aluminum case at home right now, and it works well. I have heard tell that the TK 230's are only $54 in lots of 50+ directly from TK. The 170 watt model would do it for me, but I can not find ANYONE selling these. Anyone here want to split a batch? Perhaps the market is small, but I would love to test the waters and build a dozen or so chassis-heat-grounded PSU cases for fanless PC's.
It is easier to find 12v AC-DC converters with heavy aluminum open frame housings. Perhaps these, in combination with a DC-DC ATX PSU would do the trick. http://www.opussolutions.com
It seems the people who know are not talking or else we fanless PC enthusiasts are a REALLY tiny group.
