Movie Figures and temperatures.

The best place for me to display my movie Autobots close to my computer, seems to be on top of my surround receiver. One thing, though, is that the reciver tends to give off a good bit of (hence the need for ventilation slots on the top. I didn't really worry about this while I had them displayed in robot mode, but in vehicle mode they have alot more bottom surface area and are more likely to trap heat. The bottom of Leader Prime's Truck mode seemed to get quite warm.
I've clocked the temperature on top of the reciever at about 96 degrees F. Is that enough to adversly effect movie toys over extended periods of time? I'd suspect they probably get hotter than that in semi trucks while being transported, but I don't want to inadvertently screw up my movie collection.
Also in general, aside form kids and pets (which I have neither of) what are some of the biggest dangers to Transformer Toys?
