There's 10GB of memory in the case, 2GB per motherboard, and everything is powered by the Real Power M1000W power supply. Cooling is provided by three 200mm fans, one 120mm fan, and five waterblocks + pumps with 1 radiator.
The system is powered by 5 Core 2 Quad Q9400s processors on 5 mini-ITX boards using just a PSU, with all packed inside a ATCS 840 chassis. The PSU is Real Power M1000W with 6 x 12v+ rails each fully utilized (1 for each system and 1 for the 5 x ODD plus 5 x HDD). The system comes with 10GB memories (2GB per board), 3 x 200mm fans plus 1 x 120mm fan, 5 x water pumps with 1 radiator.I'm not sure what the purpose of this system is, they did a good job at illustrating that regular users don't need a 1000W power supply but I doubt that was their goal.
