I currently have 2 4" CC on the underside of my case, I've heard horror stories of them exploding. If the current ones explode it won't get anywhere near the components. I also want to get 2 12" CC on the inside of the case, my previous case only had LED lightings, but CC spreads light better, so, how safe are they to use? I know a lot of people have them but I don't want to risk anything! Would a semi circular plastic tube over the cathodes be a good idea, just in case it explodes? Or am I just being stupid?
