Hi,

Iam JR, welcome!

Why do want a server at home? If you found your answer maybe I can help you along...

If you don't understand how to secure your router at home then is an online service beter for you. For example Digital Ocean has great products.

But a server at home can bring you a lot more:  any server, 24/7, your hardware, your policy, your privacy. For example ArkOs is a great solution in the making.

Lets begin with a Raspberry Pi, Why? It's cheap, and a nice starter for a dedicated server.
