My Core Duo iMac finally died after a period or random shutdowns and kernel panics. Now, I just can't turn it on anymore. I am afraid that the logic board is to blame which will cost an arm and a leg to repair. I am also reluctant to bring it to repair as I would not want the repairmen to have a look at my hard-disk content (photos, personal finances files ,etc.). If I don't repair my iMac and buy a new Mac, how can I retrieve my files and applications to install them on a new machine? Can I open the iMac, get the hard disk and connect to it as an external HD? I think this will enable me to get back the files (iLife libraries, Excel files, etc.). But will it enable me to get back my applications?
