Oh I'm speaking from experience with the SGI supercomputer blades. They're pretty wacky, 4x independent, dual cpu boards per blade and all sorts of weird connectors and cooling and management interfaces. Custom, centralized liquid cooling that requires a separate dedicated cooling rack unit and heat exchanger, funky power delivery with 3 phase, odd networking topologies, highly integrated cluster management software to run them etc. I'm not sure if they have any sort of software locks on top of that, but I would bet they do and presumably NCAR wipes all of them so you likely won't have the software/licenses.

I dug up a link to some of the technical documentation https://irix7.com/techpubs/007-6399-001.pdf . Probably someone can get it working, but I imagine whoever is going to go through the hassle of buying this whole many-ton supercomputer is planning to just strip it down and sell the parts.
