Just bought 4 Zotac CI323 nano’s to set up a low energy proxmox cluster.

With only 12x12cm those machines are tiny, and they only require 7 watts.

Inside I do use 16GB RAM (officially 8GB only, but it works with low powere RAM) and with a 500GB SSD from Samsung.

Thus the Proxmox cluster has 16 cores at 1.6 to 2.08GHz and 64GB of RAM, with overall around 50Watts, when using the powersave governor in Linux.

also bought two more Odroid-C3’s
