The new Quiet PC AcoustiCase™ chassis’ are a quality built PC case designed with quietness in mind and boast a combination of anti-vibration features and pre-cut acoustic sound dampening materials. Once fitted with acoustic materials and containing quiet components these cases make a very cool and quiet system and are well suited for computers with multiple hard disk drives requiring good airflow. These quiet computer enclosures are not a screwless design and this is intentional. All internals are well fastened and secured with screws to insure there will be no residual unwanted vibration or noise generated by loose or poorly fitted snap-in components found in many computer cases. The AcoustiCase™ is simply the best configured, quietest, and best built quiet computer case available any where near this price.

*Both models are also available in solid black.*
The Quiet PC AcoustiCase™ Acoustically Lined Cases are available in two different styles. The AcoustiCase™ 340 has a door which covers the 5¼" and 3½" drive bays. The AcoustiCase™ 360 does not have a door so access to the drive bays is unrestricted. We have made the chassis’ like this because some customers prefer a door while others don’t. 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.
These Quiet PC cases are 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 optimize acoustic dampening while 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.

"Given the refined styling and minimal noise generated by the test system, the Acousti Products AcoustiCase 340 Quiet Computer Case is an ideal choice for anyone who wants to appreciate what a computer system can do for them, without being particularly aware of the computer itself. The style makes it appropriate for use in an office or a living room, as it doesn't cry out for attention with bold colors, bright lights, or other gadgets that might distract from its use. Couple this with the extremely low noise operation and the entire system could become virtually invisible." Big Bruin "Tech News and Reviews".
