ATCS 840 marks the re-make of the first-ever full alloy computer chassis, the ATCS line (Active Thermal Convention System), that Cooler Master introduced to world in 1999. ATCS 840 extends this legacy with the addition of today’s latest advancement in ergonomics and system cooling. With a timeless design and unmatched attention to detail, the ATCS 840 is set to stir interest once again.


All-Aluminum Nostalgic and Functional Design
The ATCS 840 is crafted with an all-aluminum nostalgic design that captures the true essence of the original ATCS. The aluminum build not only helps accentuate the elegant design, but also provides for a lighter weight. The carefully though-out interior makes installation and housing of any computer component a breeze (including dual power supplies if necessary).

Advanced Cooling System


Starting with three monstrous 230mm fans (two on top, one in front), enough influx and withdraw of constant airflow is maintained for the entire system. The ATCS 840 is also designed with dedicated cooling for vital components such as graphic cards and hard drives (optional) to keep these heat intensive parts running stable. There is even the option to swap the top fans for internal mounted radiators for water cooling units.

Ergonomic Design


ATCS 840 comes with a slide-out motherboard tray which includes a quick CPU Cooler-remove slot for unsurpassed ease of installation. It also includes cable management and tool-free design for installation of optical and hard drives, similar to that found in most Cooler Master cases. Lastly, a washable dust-filter to prevent dust build-up and allows for easy maintenance.
