What's your server wattage? (lemmy.world)

I'm in the process of wiring a home before moving in and getting excited about running 10g from my server to the computer. Then I see 25g gear isn't that much more expensive so I might was well run at least one fiber line. But what kind of three node ceph monster will it take to make use of any of this bandwidth (plus run all my Proxmox VMs and LXCs in HA) and how much heat will I have to deal with. What's your experience with high speed homelab NAS builds and the electric bill shock that comes later? Epyc 7002 series looks perfect but seems to idle high.

Let's see...

My servers (tiny/mini/micros) in total are about... 600W or so. Two NASs, about 15-20W a piece.

I spend a out $150/mo in electricity, but my hot water/HVAC/etc are the big power draw. I'd say about $40-50/mo is what I'm spending on powering the servers in my office.

Definitely puts off some heat, but that's partially because it's all in one rack, and I've got a bunch of other work hardware in there. It's about 2 degrees warmer in my office than the rest of my home, but I also have air cycling all the time since it's a single unit HVAC and I need to keep the air moving to keep it all the right temp in the other rooms anyway (AC will come on more often otherwise, even without my rack).
