Agreed!
I've been looking into this thing for a couple of weeks now, but there isn't that much information to be found on it yet. I have found two other links. The first link provides some additional information. Link 1, Link 2

I contacted Zalman on the matter, more specifically about when it would be available, and this was what they had to say :

Thank you for your question.
The TNN500A will be on Korean and Japanes market first by September 2003. Launching time of the TNN500A to other conturys will be posted, when all seted, by our home page.

--- There is no fan in TNN(Totally No Noise)500A, also not in the PSU! so it's a TNN. The HDD noise also can not go out because 5mm~7mm thicness AL case prevent the HDD noise.
