This sounds like a potential PIC project. You'll need a couple of temp
sensors to monitor the inside air, outside air and computer temps.
Check against a desired setpoint, and decide whether to use outside air,
how much to blend it with the inside air, or to switch on the A/C with a
relay. That way, you won't have to constantly worry about it, and if we
get a cool night during the summer it can automatically switch over to
outside air.
