So, I would assume you would want enough room between the tap and the drip tray for a 45* pour.
Didn't know if there was some formula or "perfect height".
I think most people hold the glass when pouring so height shouldn't matter. Height vs stability. I would imagine you don't need it tall enough to fit a "Yard of Ale" type glass under it.
I think my tower is about 18" tall. I don't have it here to measure. The height doesn't affect the pour. Just make sure and insulate it well to keep the lines cool. There's another thread around here that goes into using a thin copper tube as a sleeve to conduct the cold air from the fridge up into the tower to keep the lines cold, you might want to check that out also.
EDIT: My "Yard of Ale" comment was NOT a result of the above post, I'm just a slow typist.
