Install Playstation???

Hello all together, have bought a radio for my mini with which I can watch dvd and also connect a playstation. I would like to do this now, but I don’t know where to hide the playstation best… optimal would of course be the glove compartment, but don’t think it fits in there. another alternative would be for me under the passenger seat, but don’t know how to fix it there best!? what do you think it would be best if you had a build?
