Yep. 9300s are very cheap now. 9400s are less cheap. 9500s are not cheap. 9600s are new and pricey. As I said, you can't recoup the ROI from the reduced power consumption, even if you're paying California or Germany power prices. Though you can definitely get the number lower! I had this system (and the 18U rack) in very close proximity in an older, non-air conditioned home for a while. So less heat meant less heat and noise. I also deliberately chased, "how low can I go (within reason)" while still chasing the goal of local NVMe performance over the network. Which makes the desire to upgrade non-existent, even 5+ years from now. Not cheap, but a very fun project where I learned a lot and the setup is absolutely silent!
