Can a Butterfly Labs Mini Rig SC cause health concerns if stored in a bedroom? Assuming heat and noise factors are not a concern, are there any additional issues (radiation) to be concerned about?

How far should this device be stored away from children's play rooms and sleeping rooms?  Can it be in a locked ventilated cabinet?

I'm trying to understand if this device, when powered on at full capacity, causes any health and safety concerns.
I don't know the actual design of the Butterfly Labs machines, but I assume that the health risks should be similar to a traditional mining rig. Probably the main concern would be the noise level of any fans installed in the machine, as well as potential electric shock should the machine be operated haphazardly and without proper grounding. You also might be worried about potential static build up, high-temperatures and overheating (should the machine gather dust over a period of time). One way or the either, the common sense would dictate that the machine should generally be safe under normal conditions, but I would keep it out of kids' reach.

Again, I have no practical experience with dealing with any Butterfly Labs hardware, and while I have a technical electronics diploma, I'm not an expert in safety or similar devices.
