Thanks for the welcome guys.
Just running a single XP1700+ @ 2.2GHz as of now, but after the heat eases a bit, I have another 4 GHz worth of parts to assemble.
Heat management will be my focus over the winter, to be prepared for next summer. I use a chilled water cooling setup, and my focus will be to vent the chiller (modded dehumidifier) to the outside.
A/C is in this room, but it is only a small unit, and would fight a losing battle against the added heat.
**Update**
Just threw together and added an XP1800+ stock air cooled unit.
3.5 GHz and counting.

This is gonna get addicting, and expensive.
