Summarising the Quiet PC/TNN 300 system is quite simple, really. It's a niche product that will appeal, in no uncertain terms, to a select bunch of users that value silence above all else. If you happen to be one of them, the TNN 300 is a pretty unique product that will appeal to you. For the rest who don't mind the noise made by a few fans, you'll wonder what the fuss is about. We try to view products in relation to how well they fit their intended purposes. In that case, then, the Quiet PC/Zalman TNN 300 system is a well-executed idea with significant practical benefits to the right type of buyer.
