iMac 1.8 Logic Board/PS Upgrade to 2.0 Possible?

I need to replace my logic board. Knowing there could also be a potential problem with the power supply (the iMac is a customer abandoned unit from 3 years ago), I may just play it safe and replace the power supply at the same time.

Is it possible to upgrade the 1.8 logic board with the 2.0 logic board and upgrade to the 2.0 power supply in an iMac that originally was a 1.8 ghz?

Just drop in the new board. The old power supply will work just fine (given that it is working at all).

You might be looking at a money pit there. The 17" and I think some 20" iMac 1.8GHz and 2.0GHz G5's had a bad batch of capacitors. I picked up a 17" off of craigslist that had this issue.

If you open up the iMac and look at the capacitors. The bad ones usually look like a scored "X" on the top of them while good ones (from what I've seen) look like a scored "K". Both the logic board and power supply have these issues.

Might I suggest (if you're good with electronics) to change out the capacitors in the power supply and logic board. Even if you buy a new (used) logic board and PSU, they might still have the issue down the line. If you really want to hold onto that iMac, check out this site
