A recent transition from a Windows PC to an M3 MacBook Air has led to repurposing older Windows PCs into a Plex-powered streaming server for accessing a personal media library. To set up a Plex server, a Windows PC should have at least an Intel Core i3 or AMD Ryzen 5, 4GB of RAM, and Windows 10. Plex is compatible only with x86 or x86-64/x64 architectures. The setup involves downloading the Plex Media Server, which runs in the background, and configuring it through a web browser. Users should create a structured file system for their media and can easily add libraries for different media types. Plex automatically fetches metadata for content, and users can connect various devices to access the server. Sharing library access with others is also possible through the settings. Transforming an old PC into a Plex server is a practical and sustainable option, with alternatives like Jellyfin available.
