Hi bro,
Why not mod your bare tank to IOS by using acrylic sheet? Plan, design and pre-cut by Dama. If your tank is acrylic, weld it with acrylic glue else for glass tank, use aquarium silicon to bond it.
FYI, when I started my reefing 10 years old, I diyed my IOS box that similar to Jireh's quick start system which work quite well for >2ft tank but same as all nano tank, need frequent water change to maintain all water parameter in good condition.
