Hi all. I lieu of my original thread (posted in the wrong section [woops]), I'm curious to know whether it'd be out of line to take in my iMac G5 PowerPC to an Apple store to see if they would cover replacement costs. http://www.apple.com/uk/support/imac/repairextensionprogram/ is what I'm referring to. My original post is as follows (which I posted in OS X instead of this appropriate forum): I am considering doing the replacement myself, but if I cause something to go haywire I'd never forgive myself. I really like that computer, but I can't trust it being on every day without me being in front of it constantly.
