Let's build an Intel N100 2U rackmount system that can be used for OPNsense or as a lightweight server! If you are looking to build a custom, energy efficient, rackmount system, this video shows one example you could consider! I plan to use this build in a future video when I do an updated full network build guide. In the long term, I plan to use 2 of these rackmount systems as 2.5/10G throughput testing clients on my network since I do not have extra mini-PCs with 10G interfaces for testing new hardware (because those systems are powering my main network and lab network!). Disclosure: This is not a sponsored video! I bought or already owned the hardware used in this project.
