Here's a couple pics of my chiller. Outer pail has 1/2" dry ice pellets and 100% Ethanol (gas line antifreeze from a local hardware store). Inner pail contains ethylene glycol, (regular auto antifreeze). I don't have a temp probe, so i'm guessing the antifreeze was somewhere around -50C for it to gel like it was. I had no insulation, so I flipped my comp on its side so condensation would drip away from the components. Risky? Probably!
