Well, if you would like to go mini (with ECC and 2.5G) you could take a look at this one:

Not totally upgradable, but at least pretty low cost and modern with an optional SATA + NVMe combination for Proxmox. Shovel in an enterprise SATA and a consumer 8TB WD SN850x and this should work pretty good. Even Optane is supported.

IPMI could be replaced with NanoKVM or JetKVM...

That looks pretty slick with a standard hsf for the CPU, thanks for sharing

Nice indeed. With only 2 nvme slots, what drive configuration do you have in your mind? Backup from nvme to HDD locally and another device remote?

For my personal purpose i would go 2 x wd sn850x 2tb RAID1 nvme(consumer)

You could also go 32gb+ Intel optane Boot and enterprise SATA data, depending on your use case
