I've built several 1U servers to colocate. One nice thing when you only have one feed and one static IPv4 address is that you can use IPv6 for management. For example, here's a server I build several years ago (pre Raspberry Pi 4): https://www.klos.com/~john/anath.jpg https://www.klos.com/~john/anath.jpg It has an NVIDIA Jetson TK2 as the main system plus a Raspberry Pi 3 that provides serial console and has a relay connected to a GPIO for remote reset for the TK2. The Pi can be reached directly via a static IPv6, so no additional IPv4 required. I also have a 1U server with an 8 gig Raspberry Pi 4 and two 8 TB drives set up as a mirror. This system is also significantly below 100 watts, both peak and average: https://twitter.com/AnachronistJohn/status/1287628712981049345 https://twitter.com/AnachronistJohn/status/12876287129810493...
