Well, the tank and scape look stunning! The cabinet does look very solid and there's very, very little overhang, so I'm betting it'll be fine, but at least you know what the potential risks are and can be prepared and make that informed decision!
The cabinets I'm using as fish stands aren't designed for that, so I've taken bigger risks and so far gotten away with it... hope that doesn't jinx me! Love that anubius coffeeflora BTW, I had to get one after seeing one too, they're so tropical looking.
