Hi,

does anyone happen to know off the top of their head (or near enough)
how much a logic board repair or replacement would cost for a 20"
1.8ghz G5 iMac.

It broke last week (sometimes won't boot at all, and if it does it
either hits an openfirmware prompt with a memory error, or just a
constant scrolling memory error, or I get an Apple grey screen with
lines across it) and Im wondering if its even worth taking it to a
repair agent.

Cheers
Richard
