I will probably upgrade the heat sinks and the fan will be mounted either on the top or the interior side of the case. I'm not a big fan of top vents for cooling. I may mount a small speaker on the top with holes for that, but the speaker will be "sealed" to the top. (The larger Apache case will likely have a vertical separator, with the paddle, headphones, and battery pack in the other half. I will probably mount the fan on that vertical partition. That way, if I spill something or it's starts raining, liquid won't get into the xcvr section of the case.) I will need some kind of cooling as the JackAl board draws enough current to heat the regulators up a bit.

I'm assuming you will be operating with the case open.? I haven't done the math but I would think unless you fall asleep on the ptt or your key I doubt you would need anything more than some vent holes in your acrylic plate.? You could upgrade the heat sinks for insurance.? If you really want a fan why couldn't you just put in the acrylic? ? --
