Enclosing Equipment Against Dust

[chipgallo]

According to the manual, the newly acquired Anthem receiver is supposed to be located in a dust-free area. I also have had to send the blu-ray player to be serviced due to dust infiltration. Looking for suggestions on an enclosure that keeps dust out but allows adequate cooling and cable management. In the photo, the 55" screen would be wall mounted, the center channel speaker would move up to the top of a new enclosure to be even with the viewers' heads and the two lower devices (blu-ray player and receiver) would be protected but still have IR access via a Harmony remote.

TIA,
Chip
