Hi!

tldr, i want to do a lot of different things. is it recommended to use one single server?

I'm planning to set up a home server and need guidance and opinions on a few things.

1. Storing Personal Media: To host images from my camera and phone.
2. Media Server/Data Backup: To back up movies that I own, along with important documents like mortgage information and taxes documents. etc.
3. Virtualization: To set up VMs for testing and various other uses.
4. Web Hosting: I'd like to run small websites that are currently running on Digital Ocean
5. Networking: I have opnsense, maybe I'd like to consolidate.
6. General Storage: For storing ebooks and miscellaneous files.

I have several questions and concerns:

• Hardware Selection: What type of server hardware should I consider for these tasks? Would it be more beneficial to build my own server or to purchase a pre-built one?
• Data Segregation and Security: How should I separate sensitive personal data from public website data on the server? Are there specific security practices I should follow?
• Storage Practices: What are the best practices for storing different types of data (e.g., personal, public, general storage) on a multi-purpose server?

Thank you in advance for your help and insights!
