ethylene glycol has a much lower thermal conductivity than water anyways (water is ~3x better).

Measuring the conductivity of liquids is practically useless, because they mix with themselves through convection or other means such as pumping. Water is 0.6 while aluminum is several hundred, yet we know water is excellent for cooling things.

The figure you want is specific heat. The specific heat of antifreeze is about half that of water. The advantage is that it is a corrosion inhibitor and is less volatile.

I really need to learn exactly how these things work. Not that I could exactly want this 40W one, but may get a small HeNe. (<5mW)

I'd seriously avoid plastics unless you've got some really good ventilation in place, for the time being. Especially plastics like ABS (Gives off hydrogen cyanide), PVC (Gives off chlorine gas) and teflon (Nasty fluorocarbons). Just a tip.
