I can't find any 10GbE NICs that use a 1x slot - if you can I'll be impressed. In theory somebody could probably make one that uses PCIe v4/5 or so, but I'm not seeing one today. If it needs more than a 1x slot, then it is all moot after that, as most consumer motherboards tend to have 1x slots, a 16x slot, and MAYBE a 4x slot in a 16x physical form. Oh, and good luck finding boards with an open end on the slot, even if there would be room to let a card dangle. My point with micro ATX was that with consumer CPUs having so few lanes available having room for more slots wouldn't help, as there wouldn't be lanes available to connect to them, unless you added a switch. That's something else which is really rare on motherboards. I don't get why they charge $250 for an AM5 motherboard, and maybe even have a switch on the X series ones, but they can't be bothered to give you larger slots. I can't imagine that all the lanes are busy all the time, so a switch would probably help quite a bit. > this is probably very restricted in > length.

That's assuming you're running network to your outhouse, and not bothering to put a switch in there (which would be more logical). > I have a four-bay NAS with server board (ASRock Rack E3C224D2I), actually my > last surviving Gentoo system. ;-) With IPMI-Chip (which alone takes several > watts), 16 GiB DDR3-ECC, an i3-4170 and 4×6 TB, it draws around 33..35 W > from the plug at idle — that is after I enabled all powersaving items in > powertop.

On a k8s box the box itself basically does nothing but run k8s. I probably only run about 5 commands to provision one from bare metal. :) -- Rich
