Hello all, I am looking for some fellow iMac G5 owners' input. I recently bought a rev.B 20" iMac G5 after having owned a rev.A for a few months. When opening up the rev.A, the three screws which hold it closed were very easy to turn and obvious when they had been tightened or loosened, as in, it was smooth turning, and then it would stop. I've had the new iMac for 2 weeks, and I've noticed that the screws are difficult to turn, and I can hear/feel a rubbing of metal on metal when turning them. They're hard to turn and it's tough to tell when they're fully loosened or tightened. Tonight I received some new RAM, and eager to put it in, I opened it up. When I tried to close it up, the screws have gotten worse, and the one on the left was not turning at all. I didn't want to strip them, and I figured this can't be normal, so I took it to my local (45 minutes local) Apple store where the guy said he hadn't had a chance to check out the new screw mechanism they came up with for the rev. B models, but he thinks it may be normal. I left it for a few days (sniff, sniff, my baby) and now I await their response. The question is how tough are your screws? The ones from the first rev. turned like butter-these are turning like....well, something that doesn't turn well. I'm afraid they're going to say it's normal, but I can't believe that and I have no way of knowing short of breaking in to the Apple store after hours and secretly unscrewing and screwing in the displays. Any input will be greatly appreciated, if for nothing more than to give me peace of mind if I have to fight about this. Thanks!
