FWIW, I decided to see how hot my player ran in my docking station before I drilled any vent holes or considered a fan. It runs fine (up to about 40 degrees) without any ventilation at all. Ambient is about 20 degrees (air-conditioned office).

So I don't want a fan. (though I understand if it simplifies your life to make 'em all the same - I could just disconnect it)

Would a kit form reduce the shipping cost? I don't mind screwing some panels together if they're all pre-drilled and stuff. I guess I'm not quite as lazy as I claim.
