Abstract
An electronic device has a rack accommodating a mother board and a first and a second printed circuit board (PCB) group mounted on the mother board. The PCBs belonging to one of the first and second groups are mounted on the mother board in an upper half of the rack while having the surfaces thereof positioned substantially parallel to the side walls of the rack. The PCBs belonging to the other group are mounted on the mother board in a lower half of the rack while having the surfaces thereof held substantially horizontal. If necessary, a third group of PCBs are positioned above one of the first and second PCB groups and mounted on the mother board with their surfaces held substantially horizontal. The wiring network between the first and second (and third) PCB groups is formed on the surface of the mother board by printing. Two electric fans may be respectively located between the first and second PCB groups and between the third and first (or second) PCB groups.
