Hello, I recently wanted to expand my home with a server that is available in the whole house, but I am a complete noob. I purchased an HP elite desk 800 g1 with an i5 4590 and 8TB of HDD space and 8GB of ram. I want this server to do numerous things:

- NAS
- Make the 8TB of space available on every computer at home and easily transfer files to and from, easy to see in windows explorer. Maybe even on android/ios phones.
- Plex/Movie server
- Split the disks into volumes and make the one volume discoverable for all smart TVs and Apple TVs where I can play movies from my server with just a few clicks on my tv.
- Back up my Pc from time to time automatically.
- Make the whole server very secure, and prevent attackers from open internet access to my files and personal things. I don't want the server to be accessible outside of my private network.
- Use a VPN on it and torrent files to it and when done transfer them to my PC.
- Use the server without a screen, connect to it and see the screen from my pc/control it remotely.
