Anyone ever removed and relocated their overflow tank?

I'm working on a little something something, and need to relocate the coolant overflow. If anyone has any tips, it'd be greatly apreciated.

 

I bought a Volvo S70 expansion tank, mounted it behind my M2 with a bracket that rests on the p/s pump bracket. Now I've true expansion chamber and I can check the water level visually. Downside is that the cap is 20 psi.

 

do you have any pictures of the setup?
