Built In Overflow Question

[MadReefer]

Saw a tank for sale with an overflow built-in. The person stated not drilled and was created by AquaOceans. Place pump in overflow compartment and add media, filter pad what. Its a big tank and sounds odd. Is this an easy cleaning process? Thoughts on this type if setup appreciated.

It’s like one of those all in one setups but limited to a small over flow. Would be ok for a fish qt setup, but it really limits the options for reef filtration is that the goal. That box would likely fill up with detritus often.

The tank is 125g why im asking. I think Fish Only might be okay but not for a reef.
