1. A temperature-controlled case, comprising:

  • a frame at least partially defining a temperature-controlled space;

    a modular door, the modular door movable about a pivot axis between a closed position and an open position for providing access to the temperature-controlled space;

    a door closing control configured to bias the modular door toward the closed position, the door closing control comprising;

    a hinge coupled to the frame, the hinge including a rotatable portion with a first cam surface and a non-rotatable portion having a second cam surface, the rotatable portion and the non-rotatable portion axially aligned with one another along the pivot axis, and a spring biasing the non-rotatable portion toward the rotatable portion so that the first and second cam surfaces engage one another;

    a torque transfer coupling including a first element removably coupled to a second element, the first element coupled to the door and the second element coupled to the hinge;

    a first electrical connector at least partially disposed within the first element and a second electrical connector at least partially disposed within the second element, wherein coupling the first element and the second element electrically couples the first electrical connector and the second electrical connector to one another;

    at least one compartment separate from and adjacent to the modular door; and

    one or more electrical devices disposed in the compartment, an electrical connection between the electrical devices in the compartment and the modular door being formed when the first element and second element of the torque transfer coupling are coupled to one another.
