These look great!
I'm not sure what impresses me more: the water-cooled EPYC, or the
passively cooled one...

Just a heads-up that I expect our reverse dependencies to have a much
higher load on the GPUs. I can easily see a typical pytorch test
stressing the GPU, for example.
ci-worker-ckk02 [1] used to be in a case but it was moved to a mining
rig because with two 3080s (when I still had them) next to each other,
cooling just totally broke down. And 3090s were impossible.
Best,
Christian
[1] I need a better name. There's two on my shortlist.
