I haven't had any heat issues at all with what's in the box now. My next thing is to rearrange a little to see if I can fit a switch in with everything else but it may just turnout to be an excuse to get another box so I can have a little more space. Back to the heat, I would think you'd be OK with that gear in one space. I might drop a thermometer into mine just to see what the actual temp is in the box. If heat did become an issue I bet with just a little fabricating a person could add some small fans to the box.
