Any suggestions on where to put the overflow box?

Getting a 48 long X 24 deep X 21 high tank. With those dimensions would it be better to have one overflow in the center or 1 in each corner? If center do you recomment 2 1" bulk heads or 1 single bulk head? I'm also thinking of having 4 holes predrilled along the back upper wall, for a return and a closed loop. What size box would you recommend? It's all custom so it's up to me.

By the way, the reason I don't want a standard 120 gal is because I don't want the height. Already have a 150 and trying to downsize to keep it fun and affordable. Will use only 175's mh and 3 110 vho's. For pumps I already have an Iwaki 40 circulation pump, and a Mag 950 for closed loop. Also have a 900 gal per hour external powerhead. This isn't as SPS tank.

Thanks for the suggestions
