Plumbing a cube that has 8 holes
 

As the title says I bought a cube that the measurements are 24" High x 24" Wide x 31" Deep with a 7" overflow so the viewable area is a perfect cube. It has 8 holes drilled into it and I need ideas on how to plumb it. The holes are like this, bottom of cube part centered in a triangle each 9" apart are 2 holes for 1" b-head and 1 hole for 3/4" b-head with the 3/4" on the right hand side. The overflow has 1 x 1" and 2 x 3/4" bulk-heads just below the water line. The 1" is in the center. The bottom of the overflow has a 2" bulk-head and a 1" b-head. I have a collection of pumps but would like to do a closed loop and hopefully only use 1 or 2 pumps.
Thanks in advance (pics to come)
