Fitting a ATO reservoir in IM 50

[albertski]

I'm debating between the Innovative Marine NUVO EXT 50-gallon and the INT 50-gallon complete reef systems (Also Waterbox EX 60.2, but leaning towards the IM). I really want to be able to have the ATO reservoir inside the cabinet (above the sump). Has anyone tried this in the INT 50? Are there any reservoirs that would fit there?

Pricey at $75.00, but very sturdy and quite thin. You could slide it behind your tank, since you will probably stay that far from the wall anyway. Then you still have room in your stand for other things. Red Sea. 4.8 gallons.
