Abstract: An electronic device configured to be mounted in a housing of a cluster, the device comprising a rear body housing at least one mother board configured to be powered by the cluster, a front tray housing at least one electronic board having at least one socket, the front tray comprising at least one fastening member for mounting an expansion card having an edge connector and a fastening portion, the electronic board being connected to the mother board by at least one flexible cable, the front tray being mounted slidable relatively from the rear body between a close position and an open position in which the front tray is at least partially removed from the cluster housing while keeping the rear body into the cluster housing so that an expansion card can be mounted/unmounted from the electronic board without powering off the device.

Abstract: A mother board with a central processing unit and two riser slots configured to cooperate with one riser card for connecting two expansion cards to the mother board. The first riser slot and the second riser slot may be connected by metal traces to the central processing unit, and the two riser slots may be spaced apart by a distance greater than 8 cm.

Abstract: A scalable system for high-power computer, comprising a plurality of motherboard chassis, inserted in a computer rack mounting kit, each motherboard chassis, being configured to receive at least one motherboard module, said plurality of inner chassis forming a stack of inner chassis, the stack being configured to receive an outer floating bracket chassis, said outer chassis being inserted by a second longitudinal end of each inner chassis forming the stack of inner chassis, each said outer floating bracket chassis being configured to accommodate at least one double floating bracket being configured to house a cable box capable of connecting the connectors of a plurality of motherboard modules, arranged in said inner chassis of the stack, to each other, the system being characterized in that the double floating bracket comprises at least several floating attachment means.
