Shadow V3 overflow against the wall photo

[Futuretotm]

Anyone have a photo of their tank against the wall with the shadow v3 on the back of it?
Just wondering how much gap will there be behind the tank and the wall.

Ie like this photo, this is my current tank

Dont have a photo but looking at synergy reef site, looks like you need 2 to 3" of space behind the tank
