Afraid not. PSU has to be installed into chassis and then that has to be connected to the socket on the wall. Switch off of course.

A case sitting on the worktop isn't grounded to anything. A mistake everyone makes, including my old college lecturer!

But why would this be a problem? All you're doing is putting yourself at the same potential as the case. As long as you're just working on the case, it wouldn't be a issue?

I remember on a TV program how engineers needed to work on live power cables so they were in a helicopter and connected themselves to the wire. This put them at the same potential (40,000v if I remember correctly) but they had no connection to ground (Due to the heli, which was also at 40,000v).

Voltage is just the difference of potential between two points.

Please correct me if I'm wrong, I'm studying Electronics after all :D
 
The computer part has been covered but I have a suggestion that might stop your daughter getting a shock...I'm guessing the trampoline has a metal frame? If so, give her something metal to hold (a key or a coin for example) and get her to touch it to the frame and I think that should discharge her

Giving her a shock you're trying to avoid in the process. Holding a metal object won't make any difference.
 
Hmm. Interesting. Just pulled my server out to install RAM and no power off switch on the back of the unit??
