Interesting. I've heard of issues with thunderbolt peripherals causing crashes when they go to sleep but never experienced it on either an iMac, Mac Pro or 2012 MacBook Pro Retina. Has apple support had anything to say about the crashes as that sounds like something that is fixable. The worrying cheap build comments don't sound fixable though!
