Broken panel repair or replace?

This is the back top corner of a 32 bio cube.
Repair or replace back panel?

I was going to drill once I gave the rim off but not so sure now.

Sorry but you are better off replacing it.
Even if you silicone a piece on top you cant get to the cracks under the present silicone.

Yea I felt that way too. I dumped that plan.(literally)

Just posted if maybe someone knew a fix to save it.

It was going great until the squared corner.


Two small sticks with fishing line wrapped around them "sawing" the rim off the top worked very well until I decided to rip it off by hand Unfortunately.
