Ok, so my shop customised 17" G5 iMac arrived a couple of weeks or so ago. I tracked it all the way from China to the UK - amazingly it all worked when I took it out of the box... until I tried to burn a CD. The machine made the most awful humming/vibration that sounded like a cross between a washing machine and a hair dryer. It could be heard in a different room. I quickly realised this was not something Jonathon Ives would design into the iMac :O The first disk burned but subsequent disks won't even burn, they just fall over after an interminable wait with some random error. I am not massively happy, has anyone else had problems like this? I am going to phone Apple tomorrow. Will they send a replacement drive out or will they courier the whole thing into base (I ordered it through the Uk Apple Store)? Lucklily I have my trusty old G4 Powerbook but still, the damn iMac wasn't cheap.
