iPad dock questions for DIY project.

I am looking at building an iPad stand that looks like an iMac, I managed to find an old iMac stand on eBay which I would like to use as the basis of this. I was inspired by the Luxo iMac iPad stand but in a more modern style, I would also like to have a slightly cleaner cable management system, so I was thinking of elongating the ipad docks support section and then attaching that to the mountings on the iMac stand.

What I wanted to know, is can some kind soul here take a few pictures of Apples iPad dock, and illustrate them with the dimensions, it would be greatly appreciated.

I will also post pictures once I have finished it.
