I'm a refrigeration/hvac mechanic and a pc gamer. I could make it happen. Chilled water is certainly the easiest. I don't ever see any sub zero glycol loops out there, but it's very possible. DX cooling has been done before, but not VRF AFAIK. That would take a LOT of money and time. On a similar note, I had a few other ideas for water cooling, like dumping the heat into the concrete slab/geo loop, or using 3 ton (ref capacity, not weight) coils instead of those cute little rads that pc's use right now.
