I posted my effort for a freestanding unit with TV on wall over it upthread somewhere. The tech (Tivo, Router, Stereo, Switch) is all in there but there is airflow under, behind and I left the back panel open where the gizmo's sit. Although naff imho wall mounted is really good for us as the room layout means both sofas are perpendicular to the telly and it can be swung to point at either, or pushed back flat where people on both can see at a 45 deg angle. With your alcove i'd do similar and you could put shelves over for rainbow organised books or objet d'art (or ugly shit one's children make.

If you were meaning an actual corner shaped unit - Habitat Max is the only one vaguely nice I found.
