non si sanno di preciso: solo che sono 5 Q9400s con relativa mobo, 2 gb di ram e un hard disk.
le mobo data la dimensione e il posizionamento mi sa che sono mini-itx
EDIT:
ho trovato questo nel web:
Coolermaster will be demonstrating a 20 cores PC over at CeBIT. 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.
Internal tests conducted by Coolermaster reveal after 5 continuous hours of full load, the hottest core reached 66C, ambient temp at 30C and chipset at 38C.
