No big deal fixin the wall. Done that before. Hauling the tank out is another story.
I have had both front flip door and the present no door. The present looks much better with the full frame, but all the work has to be from the back. Working in the tank is fine. Scraping the front glass is a PITA. And mine is only 24 wide.
The 30in. depth is much nicer looking for a picture, than my previous 25in.
Pu a Eurobrace/splash lip on any wall. I have a 3in. across the front.
