Buying a used imac Diagnostics Checklist.

[applecultvictim]

I just thought we could gather somewhere any ideas of what to look for in a used (warranty expired) imac so as to be as sure as one can that they haven't bought a lemon and they are not in for bad surprises.

Are there some diagnostic tools in terms of software?

Can you run a battery of tests to it to see how it responds?

What's the major cause of worry or failure?

Any ideas welcome.

hey dj, thanks so much for the reply but I didn't quite catch you drift? You mean not a lot of people are under apple care?

Btw, I had high hopes with your link but it doesn't load up.
