A temperature-controlled case including a base having a deck and an air flow device located below the deck, a tower having a cavity, and an air distribution system. The air distribution system includes a duct and one or more air diverting devices which permit a first portion of an air flow to be received into the tower and direct a second portion of the air flow toward the deck. Sub-portions of the first portion may be directed at the rear portions and front portions of one or more shelves. The tower includes an exterior wall having openings through which air is directed by the air diverting devices. The exterior wall may be faceted and the cavity may be segmented into channels corresponding to the facets.
