What are you doing in your “homelab” that needs a $2000 CPU? If you don’t need the PCIe lanes or memory bandwidth, get a Ryzen for 1/8th the cost and a third of the platform power requirement. You’ll get better single core IPC anyway, which is still king.
The hardware doesn’t matter. Something with 2 cores and 4GB of RAM is enough to run a k8s lab.
