To start with I suspect your homes power line or outlet has a problem which killed your iMac. The fact you feel a tingling sensation when touching the base means the case is '''hot''' electrically.
Carefully disconnect your computer from the outlet, without touching any exposed metal, as well as any thing else as you could get your self Zapped here!
'''Get an electrician in ASAP to check and fix your houses wiring'''. If he can't find anything have him check the telephone and cable entries to the building as well as the buildings grounding. What I suspect here is the ground connection is mis-wired or some device is poorly wired so the hot 120 volts services is getting into your building ground connection.

As for your computer as you brought it to a different location which we hope has good power and it still fails to startup it does should like at least the power supply is damaged. Hopefully thats all. But power issues like what may have happened in your case are hard to know if the logic board also got damaged.

As to your logic board its' serial number does not matter only the systems so you get the correct parts.
