If you guys
have any suggestions about used hardware that can be a good fit considering mainly low
noise, please let me know.
So we didn’t get these requirements initially, there’s no way for us to help you when the
requirements aren’t available for us to consider, even if we had time to consider every
one of them for you.
I think this has gone down a bit of a rabbit hole. Perhaps it would be beneficial to step
back and get clear about what exactly the OP is trying to accomplish: a cluster to just
play around with, or a cluster to serve actual workloads.
