The AVGA SR-2 Classified is one of the largest formfactors made. The build includes 2 CPU (6 cores - 12 threads each) for a total of 12 cores - 24 threads. 3 video cards, 12 RAM chips - for a total 48 Mig of ram. Mother board, CPUs and video cards are all liquid cooled by two liquid coolers with additional rads to support the separate cooling feeds. 2 power supply's with the 2nd unit powering the coolers after the PC is shut down. I have added a link to a Youtube video (one of many out there)
