The aptly-named Totally No Noise 500A (TNN 500A) is the world's first absolutely noiseless and fanless
computer case, from the number one quiet cooling
manufacturer, Zalman. With a constant desire to have the
ultimate PC comes faster and therefore noisier fans. As PC's
become commonplace in a home environment, as well as in more
specific fields such as audio and video production, so the
benefit of a noiseless system is clear. When a high
performance totally silent PC platform is required, this is
the case of choice!
