Mini NASes marry NVMe to Intel's efficient chip

While it may be tempting to go "mini" and NVMe, for a normal use case I think this is hardly cost effective.

You give up so much by using an all in mini device...

No Upgrades, no ECC, harder cooling, less I/O.

I have had a Proxmox Server with a used Fujitsu D3417 and 64gb ecc for roughly 5 years now, paid 350 bucks for the whole thing and upgraded the storage once from 1tb to 2tb. It draws 12-14W in normal day use and has 10 docker containers and 1 windows VM running.

So I would prefer a mATX board with ECC, IPMI 4xNVMe and 2.5GB over these toy boxes...

However, Jeff's content is awesome like always

I think you're right generally, but I wanna call out the ODROID H4 models as an exception to a lot of what you said. They are mostly upgradable (SODIMM RAM, SATA ports, M.2 2280 slots), and it does support in-band ECC which kinda checks the ECC box. They've got a Mini-ITX adapter for $15 so it can fit into existing cases too.

No IPMI and not very many NVME slots. So I think you're right that a good mATX board could be better.
