Ok, so my iMac (G5 Rev B) has been into Apple Care 3 times, its had its logic board replaced twice after suffering multiple daily Kernel Panics and then some big failure thingy where it wouldnt start up. The Kernel Panics are back and the Optical drive is spitting out discs often so that they drop and fall out. The Optical Drive is also not able to read occasionally, iTunes will freeze up when trying to import CDs that import just fine on a different computer. Is it worth trying to 'stick it' to Apple and try and get them to replace it? It has the Extended Warranty and we have passed the 1 year by a month or 2.
