Hi, One of my iMacs (the early series - green RevB) ... I gave the same to a friend just for sake of Word typing and complimenting interior decor Anyway, his girlfriend (!) while attempting to connect USB cable from printer to keyboard...something blow up inside (in very loud manner) Apparently, socket from where the printer is plugged, is not reliable and probably damaged. I gather this was at expense to this poor iMac Can someone give rough estimation what might have gone inside? And most of al,l is this even worth of repairing? Did someone had some similar episode?
