Putting together a home lab can be as simple as reusing an old desktop or buying a new mini PC and calling it a day, but you can make better use of older hardware you may have lying around that goes beyond full systems. It’s actually one of the most satisfying parts of building and running my home lab, providing old parts with a second life. Instead of sending everything to e-waste, we can easily repurpose older stuff to get even more from existing purchases.
