1) Yer gonna get fired (Not good in these economic times)
2) Hope you don't have a surprise fire inspection by the fire marshall, he'll have a field day
3) Sweet! :-P
4) Get some wire from Home Depot (It's about as thick as the wire a hangar is made of) and add additional support to carry the load, having that fall on someone's head is bound to get you into double trouble.
1) I hope not!!
2) I would not have put it up in the ceiling if I thought there was a chance that it could burst into flames. If it got too hot, I would assume that it would simply shut off. I also used a very heavy gage extension cord for that reason.
3) Thanks!
4) I was actually thinking of doing that. I was going to screw some wire into the plywood that the computers are mounted to and attempt to suspend it from the rafters above the drop ceiling. Although it's harder than you might expect to accomplish all of this with the small amount of access space I have.
