Cooler Master went back to the drawing boards after introducing the CM Stacker a year ago, and they have managed to incorporate the essential features of a server from the existing CM-Stacker to create the powerful CM-Stacker 810. The CM-Stacker 810 supports up to 4 CPU motherboards ranging from Micro-ATX to full size Extended-ATX. Unique power supply cage re-design to fully support standard ATX or redundant power supplies. We maximized the airflow by reconstructing the motherboard tray to support two 120mm super silent exhaust fans. Back from the root, CM-Stacker 810 will continue to have the ability to utilize up to three 120mm fan from the 4-in-3 Device Modules. Most importantly, the CM-Stacker 810 maintained the spacious interior working space and expandability from the eleven 5.25" bays from the previous version to meet and expand your imagination. Once again, the CM-Stacker 810 will put Cooler Master one step ahead of our competitors.
