It's not like there's less servers being sold, they're just bespoke designs from companies like the big Taiwanese ODMs that go straight into hyperscaler facilities, and we don't get to see public marketing websites and product info about them. The open compute platform stuff that's been publicly shown is like the tip of an iceberg.
I find it a real shame it's not easier to get OCP hardware for our homelabs. Would be so much easier to operate, upgrade, and so on. And where would you even get decommissioned OCP gear?
This is just criminal. Reusing is much better than recycling.
