Just one drive on the case or the entire case?
Yes, the controller was being replaced and it came with new drives.
Sure it can rebuild but only if one drive failed instead of the controller.
It would have been nice if customer service would have simply said so in the first place. :-)
PS: WD customer service telephoned me to follow up to my post. He confirmed what ThePizzaMatrix said. It can only RAID-1 rebuild a failed drive, and not for a replacement controller.
