If you are referring to the iPad 2 dock, then I don't think you are going to find a "dockable" case unless it's a case where part of the bottom comes off. For example, for the iPad 1 speck had a case where the back section near the port snapped back to allow for the dock, and there were some other cases where the bottom half could be removed. However, I don't think I have seen anything like this that is also compatible with the smart cover in the works, at least not yet.
