My homelab consists of 4 machines currently. When choosing them I tried to be energy conscious - using hardware which would not consume too much electrical power, while still trying to maintain the up-front cost low. These are mostly older systems and I was unable to find decent power consumption numbers for them. The specs 1x MSI Cubi 3 Silent NUC CPUDual-core i5-7200U RAM2×16GB 2x Lenovo ThinkCentre M910 Tiny
