Full layout on my forum here. Basic idea is 3 thin clients that fit within:

1u space requirement

Possibly adding 2.5gb nic to the pci-e low profile slots of each hp t740 for Ceph shared storage.

Kubernetes and/or Proxmox experiments

Adding some sort of remote management via jetkvm or pikvm or similar.

Additional expansion no doubt needed for connecting to the three nodes.

All suggestions greatly appreciated! Never done this before, but hoping to save myself from the future hassle of having to drive to the data center... would much rather log in on Wireguard and address things by remotely rebooting, etc.

Are you using it with an HDMI + USB switch or similar?
