Dead and gone then. barbu posted this http://www.instructables.com/id/Imac-G5-DIY-capacitors-repair/?ALLSTEPS but it's well beyond my competence. I have posted a question on the buying advice board. Thanks all for your suggestions.
While these DIYs can often seen daunting when you look at all the steps, it's often just a matter of going (carefully) step by step, and isn't necessarily difficult. I urge you to try replacing some of those failed capacitors- it could save you hundreds when compared to getting a replacement computer, and if you don't succeed, you are out $15 dollars, and otherwise, just as well off- $15 dollars and a few hours is all that you risk here.

Also, eyoungren's suggestion to replace the logic board is a good one. Try it if you aren't able to recap the board .
 
I would try anyway. I am not surprised that non-Apple techs won't do it since there would no reimbursement for them. From what I hear, the geniuses usually love seeing old machines. It doesn't cost anything to ask.
Those iMac are exceptionally easy to open, so you should be able to quickly check the caps for yourself as well.
My aunt brought in an iPad 1 once, the geniuses thought it was the most amazing thing in the world. Too bad it's too much work for me to bring my 512ke to a store, I would love to!
 
Replacing logic board seems slightly less daunting than doing the capacitors. However, I have found a local business which specialises in Mac repairs. If the cost is going to be prohibitively expensive, I may look into doing it myself if I can source the part here in the UK.
 
I would attempt to do the capacitors first, it costs a lot less than a new logic board

If it was me, because I'm not sure how good id be at doing something like that, it would be costing me less to buy a new board than to ruin the old one. Besides, if there is any hidden leakage onto the board, the board has likely been damaged already.

It doesn't matter if you ruin the board- it can't really get any worse than it already is. The only risk is the cost of the capacitors and some time.

Leaking capacitors likely would not damage the board.

That is true.

But if he fails to fix it, what then? Now OP is out the cost of replacing caps and the cost of a new logicboard.

From a cost perspective it's just better to replace the logicboard.

OP. If you are going with a local shop then, price out a logicboard from eBay or somewhere else. That way you aren't paying the shop's price for the LB. They have to recover their cost and they will pass that along to you.

If you simply show up with the dead Mac and the part all you are going to pay for is labour.

Ha, ha. The guys in my local Mac specialists turned out to be clowns and wanted close to GBP 200 just for doing the capacitors and when I asked about replacing the logic board, I could buy a used Intel Mac for that money.

I am going to agree that I might as well go for a logic board replacement rather than the delicate surgery involved in exchanging capacitors.

I did not get a good feeling from the local repairers. I don't think they would entertain my turning up with my own part and would probably not guarantee the repair even if they agreed to do it.

I have started the search for a replacement logic board, but they are really expensive. It would seem to be cheaper to get a 'runner' and strip out the board.
 
I found this one.

Note that at least some of the US sellers should ship international. Don't know if that's an option for you or not.
Thank you, but GBP70 is quite expensive - some ebay vendors are selling old G5 iMacs for less than that.

I have placed a want ad on my local Street life forum. Somebody may just have put their old desktop in a cupboard or in the corner when they upgraded to a new machine.

Nah they won't. I had a P4 board that a mate who was handy with a soldering iron re-capped for me. Cost me £4 for a the correct bits, and a pint of beer. Still works now. ;)
 
I won a bid on ebay for a 20" white Intel Mac. It should be here on Friday. It's a gamble, but the only certainties are death and taxes.

Thank you all for the sound advice, some of which was not really viable for me especially considering the high cost of components here in the UK and my technical incompetence.

That should be a nice little upgrade. I'm sure you'll notice the difference. RIP PPC iMac :)
