A configurable electronics cabinet cooling system includes a cabinet having multiple walls including at least one universal cabinet wall. The universal cabinet wall has a planar outward facing surface and multiple apertures. A heat transfer component is releasably connected to the universal cabinet wall. The heat transfer component is selected from either a conductive cooling member or a convective cooling member each adapted to be interchangeably and releasably connected to the universal cabinet wall using fasteners extending through same ones of the apertures. Each of the conductive cooling member and the convective cooling member includes a planar surface, the planar surface adapted to directly contact the outward facing surface of the universal cabinet wall.
