A home lab is never “finished”, there are always new upgrades to make, new services to install and tinker with, and new operating systems to try. It’s an ongoing experiment that usually starts as an old PC and can quickly turn into a sprawl of cables and devices, all of which have a purpose. Some of the biggest upgrades will obviously be flashy: a new router, new CPU for your build, or the addition of a dedicated GPU, but honestly, some of the best changes I’ve made have been small, relatively quiet upgrades.
