assuming I’m worried about a smash and grab
For your specific use case, how about this:
Get a cheap USB thumb drive and a long USB cable. Put your disk unlock password on that thumb drive, and semi-permanently affix the USB drive to your building. You said you’re in a basement. Put it on top of a rafter with a metal fitting that would keep the drive from being taken without removing the screws. Run the long USB cable from the thumb driving in your rafter to the USB port on the machine. Alter your startup script to mount the thumb drive read the password from the thumb drive to unlock your main disk. Don’t forget to immediately unmount the thumbdrive in the OS after the disk is unlocked for extra safety.
If someone is doing a smash and grab, they’ll unplug all the cables (including this USB cable going to the thumb drive) and take your machine leaving the disk encryption password behind on the USB thumb drive.
Long ago I ran a Windows Media Center PC in the living room and used the hell out of it. When WMC finally went EOL, I look for alternatives and found Plex. I never got around to setting up a Plex box, and now I see it too is ready for the scrap heap. I think this is what getting old is. You plan on doing something and never get around to it. Time passes much faster up here in age.
