The Alphacool ES 2U ServerRack was specially developed to accommodate high-performance water cooling solutions. In combination with suitable cooling, this compact 2U case can efficiently dissipate a tremendous amount of heat. To achieve this, it features a mounting bracket that supports up to a 4x80 mm full-copper radiator from the Alphacool NexXxoS series. Matching Alphacool ES 80 mm fans with PWM control are also available as an option, ensuring optimal cooling performance. Designed for versatile use, the chassis offers mounting options for a total of four 5.25" drives at the front, with two on each side. Additionally, a status front panel with USB connection option (item no. 25054) can be installed here. Two different slot brackets as well as five additional brackets for various power supply types are included. A special highlight is the newly developed rail system, which makes installation and maintenance of the system?whether in a server enclosure or open frame environment?significantly easier. Additionally, the bracket for the radiator and fans can be flexibly adjusted inside the case to suit individual builds. Alphacool also offers specially designed, pre-assembled water cooling kits for this server rack that can be configured to customer requirements. Note: The case is supplied without an I/O panel. A matching set including the I/O panel and cable kit is available separately under item number 25054.
