A processing cluster comprising: a mounting structure comprising a plurality of spokes extending from a spindle to a peripheral ring, wherein the spokes are separated from each other by apertures, the plurality of spokes each having a mounting surface extending perpendicularly from the spindle and having a plurality of receiving apertures configured to receive locating pins to couple a base portion of a bracket of a bracket-processor assembly to the mounting surface; and a plurality of bracket-processor assemblies, each bracket-processor assembly comprising: a bracket for supporting a processor, and a processor mounted on the bracket, the processor having a major surface and a first edge; wherein each of the brackets comprises: an upright portion configured to support the major surface of the processor mounted on the bracket, the upright portion comprising a first arm and a second arm, the first arm being substantially parallel to the second arm; a base portion configured to receive the first edge of the processor mounted on the bracket, wherein the base portion comprises a ledge extending substantially perpendicular to the upright portion; an offset member extending substantially perpendicular to the ledge, wherein the offset member is configured to space the processor mounted on the bracket from the ledge; and a locating pin extending from the ledge in a direction distal to the first arm and second arm, the locating pin being configured to couple the base portion to the mounting surface of a spoke of the mounting structure such that processors mounted on the brackets are mounted perpendicular to the mounting surface of the spokes to which they are attached. a mounting structure comprising a plurality of spokes extending from a spindle to a peripheral ring, wherein the spokes are separated from each other by apertures, the plurality of spokes each having a mounting surface extending perpendicularly from the spindle and having a plurality of receiving apertures configured to receive locating pins to couple a base portion of a bracket of a bracket-processor assembly to the mounting surface;
