Modular solution. Big NAS for backup and file and media serving shuts down when I go to bed automatically or nobody is home. Boots via WOL when needed.
Always on services on a central pi for home automation, phone and internet services, etc.
I’m surprised nobody here mentioned SoGO. It’s a fully featured web mail interface that integrates contact management and a web calendar including caldav, carddav and task support. Easy up setup and easy to connect to any phone via foss apps.
Suse Linux before it was opensuse
I use SoGo for that.
Cal and task sync. Card dav, Email und calendar in one neat web interface
I can attest to that. Parents tried Linux to prevent me from gaming. Learned to dual boot first, got into security and Linux later and am engineer today. N+=1
