A completely silent computer

I've been trying to make my computers quieter for nearly three decades. Custom liquid cooling loops, magnetically-stabilised fluid-dynamic bearings, acoustic dampeners, silicone shock absorbers, you name it. Well, last week I finally managed to build a completely silent computer. Without further ado...The Streacom DB4 is an amazing chassis and case, which I am considering for one of my next computer builds. This article provides great insight into building such a fanless PC, with links to additional articles about the system later in its lifespan.
