My set-up might be a little out of the ordinary. Yesterday, we moved a few of the components taking up space in the living room to the coat closet that shares a wall the TV is mounted on. Cables are hidden in the walls, and I'm very happy with how the project is working. I let the components sit in the closet overnight while they were on standby. It's a little warmer than usual, but not warm to the point that I'm worried about a fire hazard. Actually, not even close. I'm considering a redundancy in ventilation. I was toying with the idea of attaching a PC cooling fan to the shelving unit to get a little bit of circulation. Albeit, there isn't much fresh air to circulate in the closet. However, I thought moving the air around even a little bit would help. Of course, I could be overanalyzing this whole thing. Many illustrations I've seen involving the infrared repeater I picked up showed devices in cabinets that are much, much smaller than the coat closet. Thoughts?
