Abstract: A mounting arrangement for mounting and supporting a plurality of cylindrical form or other computer systems having specialized physical form, for example Apple Mac Pro computer systems, in a data center, so as to optimize placement, cooling air flow, access to cabling, and maximizing use of space. The disclosed arrangement provide for mounting up to 16 Mac Pro computers or similar devices on a single shelf, in a horizontal position, up to 8 shelves, for a total of up to 128 Mac Pro computers in a single rack assembly, with accessibility from both sides of the rack, and convenient arrangements for power and communications cabling, as well as generally vertical cooling air flow.

Abstract: A data center mounting rack for mounting and supporting a plurality of generally rectangular small form computer systems in a vertical stacked arrangement. The shelving arrangement comprises a pair of spaced apart vertical end panels supporting a plurality of horizontal mounting shelves. Each of the shelves includes a pair of rows of spaced apart first openings extending along the length of each shelf, for allowing the passage of cabling for computers and for permitting cooling air flow. Each of the shelves also includes a plurality of rows of spaced apart air flow openings in a staggered arrangement. Each of the shelves support a plurality of U-shaped computer system mounting brackets. Each of the mounting brackets supports a rectangular small form computer system in a vertical orientation such that air flow is directed along the top surface and bottom surface by the air flow openings to aid in cooling.
