Buying a used server motherboard, especially the dirt-cheap models, can be a great start to your home lab. You get cheap access to enterprise performance and features, and can run all the self-hosting services you’d want. And dual-CPU motherboards can power your virtualization and high-end multi-threaded workloads without you worrying about upgrading to something more powerful anytime soon. That said, the process of securing a used server board is often marred by uncertainty — make sure you do your research and know exactly what you’re buying.
