VM engineers have the superhub's and TV boxes on the van, they' bring them on the day.
As for putting it where you want, depends on the engineer. A lot of them are friendly.

If you've not had cable before he'll look at what you want and take it from there. Until they start the work there's no saying where the cable will be run outside, The box on the outside is only a cover for where the cable runs in through the wall.
