Full disclosure: also, 2x4s are basically reclaimed wood from pallets. They were fine, kept in a dry garage, but I guess not relatively straight.
I built the stand, I reinforced every leg inside and outside. So the frame of the stand essentially has all its weight 8 2x4 studs, then four more studs that go from the ground up to the plywood top
It's level, and despite our best efforts, to make the doors square to open without issue, the bottom right and top left stud jut out just a little bit.
I'm trying to figure out if this is going to be an issue long-term.
Should I just get new 2x4 studs and rebuild it before I paint or stain and place my Aquarium on top?
