I set up a VSCode server on my Raspberry Pi, run rclone bisync every half hour which syncs text files with a designated folder on my Synology NAS, and I can have access to all my notes, which are all text files.

With that much RAM, maybe buy a few NAS drives during Black Friday and use it as a NAS. Get an HBA card if you don't have enough SATA ports, and put TrueNAS on it. ZFS loves lots of memory.
