Let's start with the specs of my server:

• CPU: 8 x Intel(R) Xeon(R) CPU E3-1240
• RAM: 8GB DDR3
• SSD: 1TB
• HDD: 1TB

My server is running Proxmox. And I use it to host:

• Immich: A Foto Backup Service
• Syncthing: A File Sync Service
• Wireguard VPN
• Twitch Channel Point Miner
• Pi-Hole: Network-wide DNS based Adblocker

And a lot of other stuff.

(The SSD has been build in safely :)
