The Quiet PC AcoustiCase™ Case Design
The AcoustiCase 340 has a door which covers the 5¼" and 3½" drive bays. The build quality is exceptional with all removable cages fitted securely, preventing annoying rattles and hums. In addition, all edges have been rounded making this case a joy to work with. Internally the AcoustiCase™ is spacious and has a "no tool" easy open side panel for quick access.
Pre-Cut Acoustic Materials
This Quiet PC case is supplied with pre-cut specialist soundproofing materials with comprehensive fitting instructions, and an online fitting guide with images for easy assembly. The acoustic materials have been carefully designed to optimise acoustic dampening whilst allowing the air flow necessary for cooling.

These pre-cut acoustic materials are specially designed by Acousti Products and are made from the highest quality professional studio-grade materials. They are non-shedding and therefore do not crumble or generate dust. Their high density improves sound absorption, ensures a low flammability performance and allows for the dual-layer composite that is used to line the sides of the case.

(8/10)
Great case slightly let down by a flimsy plastic door and power button. However, those two issues do not overshadow the fact that this is a great case. The soundproof lining really makes this case very quiet. And it is affordable.
