I would like to start and create my first file server at home. I’ve never done this before and I’m a beginner. I would like to know how to create one, how to maintain it for years to come, and what costs are entailed with a direct or indirect costs. Thanks everyone.

Edit

Added the below for clarity.

What I am looking for is a way to storing my personal files at home. I am not looking for internet connected device that I can access remotely.

It will be mainly used to store my personal photos and videos, and not used to stream movies to a device.

Should be accessible by devices such as android, windows, and iOS.
