The Alphacool ES 2U ServerRack has been specifically optimised to accommodate water cooling sets that can dissipate up to 880W of waste heat in this enclosure. For this purpose, the enclosure not only offers a mounting frame for a maximum of one 4x80mm full copper radiator of the Alphacool NexXxoS series. The optionally available Alphacool ES 80 mm fans with PWM control ensure optimum cooling performance. Drives The 2U server rack offers mounting options for four 5.25" drives on the left and right side of the front. Alternatively, each 5.25" bay offers the option of mounting three 3.5" drives via an enclosed adapter. A mounting frame for mounting up to six 2.5" drives is possible in the centre front. The mounting frame for the 2.5" can also be mounted in other places in the case. Mainboard For mounting an SSI-EBB mainboard, all the usual screw connection options in the classic ATX format are available. This includes all mounting holes for Mini-ITX to EE-ATX. The case offers space for up to seven 0.8" low-profile cards. Water cooling for 880W waste heat With an appropriate water cooling system, up to 880W of waste heat can be dissipated in this case. Alphacool offers special water cooling sets for this purpose, which can be individually configured and are delivered to the customer pre-filled. Please note: The case comes without I/O panel. Alphacool offers a separate set of I/O panel and cable harness under item number 1021066.
