I see this is California. In Northern California he might get away without a whole lot of A/C if he just ventilates the garage. The energy police might like that better. PCs are really a lot tougher than the "computers" of old. They don't need that "glass house" environment. I have had one in my car for almost a decade, cranking up at 120f or so whenever I get in the car in the summer. There is also one that has lived in my garage for almost as long, including surviving a fire.
