I have also assembled and started painting a Land Raider Proteus fto carry around my Gorgon Terminators (this is the only shot I have of it right now). The Cataphractii Terminators will be in the Phobos so I won't forget which unit is in which transport on the tabletop. 

I have to say this is a much nicer kit to put together than the Phobos Land Raider, the parts just fit together much better. I have started painting and will post a photo of the progress soon.
