What my setup will soon be for hardware: Gen 2 AMD epic 16 core CPU, Supermicro motherboard with lots of pcie slots, 128g ram, Intel arc a40 GPU, HBA card attached to a super micro disk shelf
Software: Proxmox for host is, Truenas Scale (just NAS) in VM with HBA card passed into VM, Plex in VM with Intel GPU passed in, 3 VMs for docker swarm (headless Debian)
Other thoughts: Cloud flare will only be helpful for things you want exposed to the internet. If you do that make sure you have a reverse proxy. This is how I expose services for non-tech family.
VPN will be more secure, but can also be more of a pain. I generally only do that for things only I need or only techy savvy people will use.
I have started to mentally replace “what doesn’t kill you makes you stronger” with “every hurt you heal makes you stronger”. I am sorry you got hurt, I wish you the best on your journey to heal.
