Interesting, let us know how that goes.

I'd be particularly interested in what you guys decide for a cooling medium. I'm a little paranoid: water cooling -- even distilled, deionized water -- makes me a little nervous around electronics. (Even if the components are not directly exposed to it. Fittings sometimes leak!) I would think a very low-viscosity nonconductive oil would make a good coolant, though I can imagine that it will never achieve as many BTU-transferred per unit volume as water does.


Annnd.... now I've gone completely off-topic...
