Abstract:
In a modular tower for storing tandemly-positioned computing system devices at modular blocks of the modular tower, an input/output (I/O) bus assembly connectable to the computing system devices contained at the modular blocks, said I/O bus assembly comprising:a plurality of printed circuit boards, each positioned at one of the modular blocks of the modular tower, each printed circuit board defining a top edge surface, a bottom edge surface, and a side edge surface, the top edge surface of one of the printed circuit boards positioned at a first one of the modular blocks abutting with the bottom edge surface of another of the printed circuit boards positioned at a next adjacent one of the modular blocks;a plurality of bus lines formed to extend along the printed circuit boards positioned at each of the modular blocks, a bus line of said plurality of bus lines extending to the side edge surface of each printed circuit board to be distributed therefrom and other bus lines of said plurality of bus lines extending between the bottom edge surface and the top edge surface of each printed circuit board; andan edge connector for connecting together portions of the plurality of bus lines formed at the top edge surface of one of the printed circuit boards with portions of the plurality of bus lines formed at the bottom edge surface of another of the printed circuit boards positioned at the next adjacent one of the modular blocks.
