Well its been a while.
While living in Thailand, in an apartment got to about 40c in the day sometimes and with a fish tank that I was not able to use due to body corporate idiocy, I converted it into a cooled wardian case. This was using the fish tank, lights, an aquarium water chiller and a mile of tubes and other bits and pieces.
I am now back in Australia and have modified an old display cabinet along the same lines. The water in a reservoir is chilled to 18c, and pumped (from a smaller pump) into the wardian case to filter through a radiator with fans. The air blowing over the cold radiator chills the air in the case to a nice 22c and now its winter to about 17c at night. It oddly seems to stop the temps dropping too low also. I presume even though its cool, the radiator is at night warmer than ambient in the room.
Here are some photos.
The case with the 150 watt metal halide (5700K tube). I cut a hole in the top of the case to fit it. No heat gets in as the case has a glass false ceiling.

The shelves made from egg crate and some bonding glue.

The chiller, reservoir.
The radiator fan (computer cooling radiator that I have powered by a laptop power source.)
Pipes going in.

Partly stocked up. Housing a lot of seedlings now until they get going in mounts and can go home to the greenhouse in spring. Doing very well with Polyrhiza lindenii seedlings, along with Psychopsiella liminghii, Sophronitis cernua flava, Bulbophyllum tingabarinum alba, Laelia alaorii, Nanodes medusae, various Lepanthes from flask, a few Masdevallia, Trisetella, Restrepia and others.
