One of the ultimate goals of a Home Theater PC enthusiast is to achieve a completely silent appliance. There are several ways to achieve this by using low-power motherboards, solid-state drives, and cards that only require passive cooling. Although the components you choose in your system plays a significant part of its silence, the next level of noise reduction is reached when you apply sound dampening material inside your computer.
A lot of testing and research has been done by many companies to come up with acoustic material to silence your PC or home theater rig. One of the high-end materials comes from Acousti Products, who asked us to test their AcoustiPack Ultimate material, along with their AcoustiPack Extra foam.
