    Ok guys. I got this beast yesterday. I installed OWC-ram and Samsung F1. Everything´s fine, except the resonating every 5 seconds and, of course, the booting after waking up. I think that the resonation comes from the PSU, not for sure. It´s very irritating. What can I do? I don´t want to open that PSU by myself because that´ll avoid the warranty. Need to call Apple? The box really was taking hits, it was far from nice, but I can´t believe that the computer can take hits, because it is so well packed inside.

    Well, any other have this resonation-problem?

    The resonating noise, you sure it's not the Samsung? Does it happen once every 10-15 mintues?

    Boot off the install DVD without the drive(s) in the machine?

    That would eliminate the drive(s) as a possible source.

    No, it´s happening once every 5-10 seconds. So are the fans, they´re getting more rpm once every 5-7 seconds. That´s really weird.

    I´ll do that. I´ll come here to report then.

    Mine does that from time to time. Give it a sharp tap on the top.

    I had a resonating issue on my 2 x 2.66 Dual-Core. When it would happen, if touched the side or top of the machine it would stop. I took out each drive, tightened the screws that held them to the drive cage, and reinserted them. Haven't had the problem since (probably a year ago). Since you think it is the PSU, not sure if this is any help, but wanted to let you know.

    I'd say it is on a hard surface and stick a cheap $1 neoprene mouse pad, or some other resonance damping produce under the feet.

    I hate the resonating beat frequencies.
