I'm not really sure if my problem is "home improvement" enough, or is too much 'hobby', so I thought to check over @ meta.DIY first :)

Without producing everything here, the question is basically about mounting a tablet to a wall (kitchen) to create a media center // remote for media server. Networking, software etc are all fine, the only problem I still have is the actual mounting-on-the-wall part, options I have concerning rotation, etc etc.

Would this be considered off-topic? I think it fits the bill here, but on the other hand, I'm not sure I would have "asked a home contractor" this.
