I'm kind of a Fujitsu fanboy. Since i came across the fact that a pretty modern xeon ecc ram nvme Workstation boards can be optimized to only draw ~10 Watt idle is just impressive, that is less than a gaming router. Even older ones like D3417-B12 were crazy effizient.

I also liked their Primergy Servers, but never got one for a reasonable price to test it out.

Another thing was the Futro series (e.g. S930) that could be used as opnsense firewall or low budget proxmox host.

Unfortunately it was always hard to obtain the high quality stuff as a consumer and years ago they sold their mainboard section to kontron. So no new Fujitsu Mainboards for now... What a pity.
