Pittsburgh cases are also good bang-for-the-buck. I have had Doepfer cases (back in 1999-2002), the Mantis (when I got back into modular in 2017) and now a Pittsburgh Structure 360 plus a separate 104 Palette. I love the Pittsburgh case... but it's also wildly larger than the OP was looking for, so I didn't mention it.
If you can find one used, I also really love the form factor of the Pittsburgh 270 case. But it's also very close to the same as the Doepfer LC9 case (just 18hp larger), and significantly more expensive.
