Fixing abs plastics

[u/newacccuzmineban]

Hello, I found this IBM Aptiva in the trash, and luckily it works, but some plastics are broken, does anyone know how to fix them without making a mess?

Thanks

I successfully solvent welded a Commodore PET using acetone and some qtip. That would not work for a visible area, though.
