Do you really need an integrated GPU for GPU purposes? If not, consider the Asrock Rack X470/X570 motherboards + a 5950x or something. They come with real IPMI, explicitly support ECC, and have an onboard VGA output driven by the BMC.

AM4 CPUs have also gotten really cheap these days for how much compute you can get out of them. The only downside here is that the board is relatively expensive.

It’s also worth pointing out that DDR5’s on-die ECC (this is what you get on consumer platforms running consumer RAM) does not provide the same level of ECC protection as the traditional DDR4 ECC UDIMM/RDIMM (and prior) implementations.

Alternately, do you really need this level of performance? “will only be used for network storage access” suggests that you could get away with far far less CPU performance. If it’s truly only used for ZFS and file serving from HDDs, then you could go as old and as cheap as Haswell or Skylake and still have enough performance.

Looks like a Seagate drive. It’s just the way Seagate presents the data.
