"The SilverStone TJ10 ESA Edition Case improves on the regular TJ10 case in that it's ESA-certified. The Enthusiast System Architecture (ESA) is the industry’s first open-standard PC monitoring and control protocol for real-time communication and control of system thermal, electrical, acoustic and operating characteristics. This case is very well constructed, made from solid aluminum, has fantastic air circulation and the motherboard tray is removable. It's simply one of the best cases money can buy!
