Zalman TNN-500A Fanless PC Case Review - Conclusions
(Page 10 of 10 )
The TNN 500A is one of a kind. It has a love it or hate it look, but it does what it says on the box. It is impressive, it is unique, it is of superb quality and, most importantly, it is quiet, quiet, quiet. Is it worth the hefty price tag? Only you can decide. There have been one or two other minor reviews of this Zalman case on the net if you want some third-party opinions.

This site says:
"Ja was soll man da noch sagen, ein Sahnestück der Superlative. Da bekomme ich feuchte Augen. Heatpipes (18 Stück!!) und Kühlkörper bis zum abwinken. Ruhe in Vollendeter Form da es ein in sich völlig geschlossenes Gehäuse ist. Das erste PC Gehäuse wo man auch die optischen Laufwerke dämmen und entkoppeln kann ! Mehr ist technisch nicht machbar! Leiser gehts nicht!"
I think they mean that they like it.
Google's translation of that page:
"cream of the superlative. ... I get damp eyes. Peace in completed form ...More is technically not feasible! More quietly it gets not!"
Geddit?
TrustedReviews.com says:
"So why is this case so special? Well, for starters it’s not beige, but much more importantly, it is completely noiseless ... With the complete removal of cooling fans it is truly a ground breaking product"
Hexus.net says:
Quietness is generally a subjective issue, yet I feel confident in stating that the Zalman / Poweroid combination can't be heard above normal background noise. It's nice to hear birds chirp 30 feet away. It's nice not to have to dial the stereo up when listening to music, and it's nice that such quietness can be achieved without having to compromise performance.
ZDNet says:
"We were impressed by the Poweroid 1200, which does its main job – near-silent operation – very well indeed....if you really need a quiet computer, then a PC built around the Zalman TNN 500A case - such as the Poweroid 1200 - is currently the state of the art"
How much does low noise mean to you? If it's really that important, there's no choice. This is the only quality, completely fan-less case on the market. It represents a tremendous amount of engineering effort to produce a product of this caliber, and considerable financial risk.
