CARD RETENTION MECHANISM

A system can include a chassis; a board operatively coupled to the chassis where the board includes card slots aligned along respective parallel planes and circuitry operatively coupled to the slots; a processor operatively coupled to the circuitry of the board; memory accessible by the processor; a bracket operatively coupled to the chassis where the bracket includes parallel recesses corresponding to the parallel planes; and a retainer operatively coupled to the bracket where the retainer includes parallel recesses where in an open orientation the parallel recesses of the retainer align with the parallel recesses of the bracket and where in a retention orientation the parallel recesses of the retainer misalign with the parallel recesses of the bracket. Various other apparatuses, systems, methods, etc., are also disclosed.
