40B AIO

[.OptimusPrime.]

I picked up a 40B from the dollar/gal sale that I want to turn into an AIO. I want the overflow to be on the side wall instead of on the back. 

 

Here is the layout (crude ms paint) that I have for the false wall and compartments. I want the wall to be about 6" away from the glass to give me ample room to get in there if need be and doesn't take away took much real estate.

 

Both the skimmer and media will sit in the overflow compartments on either side.

 

 

Any thoughts or ideas on how to improve this?
