I found 2 "official" responzez in Zalman'z forumz regarding the TNN500A:
#1:
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.
> No fans ANYWHERE in the case (except for PSU), so it's whisper-quiet !!
--- There is no fan in TNN(Totally No Noise)500A, PSU also! so it's a TNN. The HDD noise also can not go out because 5mm~7mm thicness AL case prevent the HDD noise.

Thank you very much for your fervent interest in Zalman's upcoming product.
Q: Will it be available for AMD as well?
A: Currently, Intel socket478 and AMD socket754 are supported. We are not planning to support older platforms at this moment.
Q: Will it be possible to purchase only the case with the cooling solutions?
A: TNN500A package consisits of a case, a 300W (or 400W) No Fan PSU, cooling solutions and some accessories. PC components, such as motherboard, CPU, memory, etc., are not included.
Q: I understand it might be hard to transfer the CPU heat with heatpipes due to the many motherboard designs, so how flexible is it?
A: Not all motherboards having compatible platforms fit the TNN. About 95% among the latest motherboards are suitable. We'll publish the "Recommended motherboard list for TNN500A".
Q: More than 300w PSUs available? If not, is it possible to use a PSU not made by Zalman?
A: TNN 500A which is being introduced on the web has the 300W No Fan PSU made by Zalman. Higher capacity model, 400W, is being developed and will be available in near future.
