So how did you propose to get the heat from the equipment
to the car-radiator door?

The idea of making the entire room into a refrigerator by
bringing coolant to the racks is a good one, but I think
that for this to be successful, more attention needs to be
paid to physical placement of things, and the chillers need
to be broken open. By that I mean that chillers cease to be
a big box at the edge of the room because they are now part
of the room itself. Think of a flat chiller attached to the
ceiling with spaces for racks to be inserted into it.
