Proxmox VE on a machine that I got almost for free. Intel i3-4160, 10GB RAM, 240GB SSD for the OS, and a non-redundant 1T HDD for storage. The only things I paid for are a second NIC and an 8GB RAM stick.
PVE is running a pfSense VM, and a bunch of Debian containers:
- Samba
- Jellyfin (still setting it up)
- Twingate Connector
All internet traffic goes through the pfSense VM. Unfortunately the ISP has put me behind CGNAT and disabled bridge mode, so my internet-facing things (mostly Wireguard and SSH) are pretty much crippled. Right now my best no-cost option is to use Twingate, but I don’t trust it to handle anything other than SSH.
