my first 120 build.

So i finally got a 120 off a buddy of mine that came with a HOB overflow, ( i hate them ) But i finally got my marine depot elite large overflow kit and i was wondering exactly the location where to mount the overflow,
My tank size is
48''Long,
21''Tall with trims,
18''Wide,

My stand size is
25'' Wide
51" Long
52'' Long touching the wall,

The marine depot elite overflow kit is
12'' Long
3'' Wide
6 1/4'' Tall with lid,

I was thinking of putting the overflow box on the side of the tank closest to the wall in the center and running 2 return lights from the pump one on each side of the overflow box, What are the pros and cons of running it like this?

My idea is something like this.
