If you saw how big the regulator assembly is you might change your mind
A manifold is much easier to orientate. For example - I have mine oriented with a bracket I fabbed up so that the outlets of the ball valves point horizontally. There's no way I can do that with this setup - it's far too heavy and too big. If the lines came into the keezer horizontally it would be no problem. I am very shortly on vertical spacing - my kegs fit tight.
