Note sure if the heat is good for the wine ...
Heat rises...besides, I'm a beer drinker.

In any case, it's not a permanent setup. I just wanted to get the GPUs out of the room they were in previously; that room was getting unbearably warm.
Might just yank the GPUs altogether once the Bitfury hardware arrives; it'd lower my electric bill a fair bit. (A Raspberry Pi is bundled with it...wonder if I could have it handle the BFL hardware too, since the Bitfury is connected to it through the GPIO port.)
