Got back a bit ago. Had a bit of luck. I reproduced the crazy buzzing sound for the Genius at the store. That was the easy part. But then the Genius said they he no idea when the logic board would be available for repairing my system, but that I could take my system home with me and come back when it was in stock! I said WTF!!! I wiped everything, not to pack it all up and drive half an hour to be told to come back at SOME point. I even asked them yesterday on the phone if they had the logic boards and they said they did! Gah! That, and that they had never repaired a new 27" did not sit well with me, so I told them how displeased I was with the service. (I'd also had a bad experience on the phone with AppleCare the night before, which was documented - and aided my case).
The Genius went away and came back with the manager. The manager apologized for essentially wasting my time. He said he had a new system in stock that had just come in, but it was slightly different to mine.
The one in the store:
3.4Ghz i7, 8GB, 1TB Fusion, Geforce 680MX 2GB
Problem is mine was just the 1TB, no fusion.
That was a $250 upgrade, of course...
The manager then asked me if I would mind splitting the difference between my unit and the fusion-equipped unit. I said OK.
Somehow, the difference in price came out to be $91.99 to go from the non-fusion machine to the fusion machine (I know, wtf?). I wasn't going to look a gift-horse in the mouth, and said thank you.
Even better, he let me keep my Magic Trackpad, since the default Apple high-end config came with the Magic mouse.
So, $91.99 later I have a new fusion-equipped iMac, and I got a free Magic Mouse.
Even better, there's no buzzing on this new system when the GPU is under load. So, so far... so... good (not wanting to get ahead of myself, but this system really is doing better so far).
OS X is still installed on my Thunderbolt 256GB Samsung drive, but I split the fusion disk and installed Windows 7 on the SSD part. So now both Windows and OS X are on SSDs. WIN!
Must... keep.... positive!
