RTX 4060 + 64GB RAM: Can I run 70B models for "wise" local therapy without the maintenance headache?

Hi everyone, I’m looking to build a local, 100% private AI setup that feels less like a technical assistant and like a warm, therapeutic companion. I’ve done some initial research on a hardware/software stack, but I’d love a second opinion on whether this will actually meet my needs for deep self-reflection without becoming a maintenance nightmare.
