Running a BitTorrent (BT) or Private Tracker (PT) server at home can be challenging if your home network doesn’t have a public IP. Public IPs are essential for direct peer-to-peer connections, which significantly improve torrent connectivity. However, with the right setup, you can achieve similar connectivity and even gain extra benefits, like access to IPv6 peers, by using a VPS and WireGuard.

This model stands out for its upgradeability: it allows for both memory and storage upgrades, making it particularly versatile. It’s also the last Mac Mini model with this flexibility, as the 2014 model saw soldered RAM, limited CPU performance, and eventually, Apple’s transition to ARM architecture in later versions, which limits virtualization capabilities.
