Who's setup is that?
Mine!
I Built This Two-Stage Phase Change back in 2004 when I was HEAVILY into Multiple Stage Systems for Sub-Zero Cooling My ABIT IT7 (as in the Photos) with an Intel 3.2 ES (LGA 478).
It uses R22 for the First stage that MUST bring the Temperature down below -50C in order to get the Second stage that uses Ethylene Gas (Yes, It can be used as a refrigerant) to be able to Start Cooling Down to -100C.
It was Fun Back then, But I haven't built any more Multiple-Stage Systems and have been content with My Single stage Setups.
If I want to get that Colder than -100C again, THEN I would Talk to Nate about some Pots!
