Accidentally plugged into 220V outlet, what can I do?

My husband accidentally plugged this computer into a 220 V outlet. There was a loud pop and a spark at the base of the computer. What might be the best bet for attempting to fix it? Replace the power supply? Based on your experience, does this ruin more parts (i.e. logic board)? I want to know if it's worth spending the money trying to replace the power supply, or if that money should go toward a new computer.

The power supply probably died, if you didn't turn it on while you plugged it in, then other components probably not affected. iFixit sells power supplies for these computers.

The power supplies in these though are the same for both 110 or 220v, so plugging into 220v should have no ill effect (we do it over here in the UK everyday...).

They are known for their weak capacitors though, so the extra voltage probably finished them off, one of ours here went pop & bang with a power surge two years ago, unfortunately it needed both the power supply & the logic board.

The iMac G5 does not have a dual voltage supply, so it was blown; hopefully nothing else was harmed.
