STH Project TinyMiniMicro is set to revolutionize the home lab segment with clusters of high-quality, quiet, low power, and inexpensive nodes. We have purchased tons of second-hand Lenovo Tiny, HP Mini, and Dell Micro nodes to see what each offers in terms of power, performance, noise, and expansion. In this series, we are going to cover the nodes themselves, but also important aspects of the lifecycle including purchasing second-hand units.

By purchasing so many, we have found a number of variations and deviations from what we would have otherwise expected. In the process, we found that these units offer enormous value, but there were a lot of pitfalls (and nice surprises) to purchasing so many used units. Our goal over the series is to help you understand what to look for so you can learn from our mistakes purchasing a large population of these.
