Cooling solutions which purpose is not solely to achieve low temperatures are getting rare today. If you want a silent computer, you need to get parts from different stores and manufacturers, with nobody having everything you need. A while ago, Zalman showed off a passively cooled case, but since then not much have happened the last months. NordicHardware proudly presents the first (?) vast preview of this case that Zalman refers to TNN500A (of which the former part is an abbreviation for Totally No Noise). It is more or less a hefty 25 kilogram heatsink with just enough room for computer accessories. How this is possible is explained later on in the preview. This is a prototype of the case, hence they're are not allowed to publish any benchmarking results with this system. A review of the final version will be done later on, but until then you'll have to settle with this preview.
