Yes, I don't see the folks being too keen on having them in view. They're hardly visually appealing. (Ok, I like them, but think of it from the 60 year old perspective - different matter entirely). So they'll be indoors. But the sides of the cabinate will have angled slats or something similar to allow free movement of air. It'll have to, and maybe a couple of fans, towards the top, to remove hot air and encourage cool air from below to enter the enclosure. I know the Onkyo's run hot, but I think with sufficient air movement it should be ok. Would you agree with that Clare?
