I think I'm going to place my order for the SM X13SAE-F and RAM today. This looks to be the best match for my home sever needs, all things considered. Looks like the price of that RAM at Wiredzone also dropped a few bucks, down to $193, still expensive!
Curious, are others in this thread using this platform for home server needs? If so, what OS are you using (or planning)? I think my plan is to pair this MB with a 13700k, disable the E cores, and either run TrueNAS Scale, or a DIY Ubuntu "perfect media server" heavy on ZFS and Docker, or maybe a container-focused distro like RancherOS... or maybe ESXi on bare iron with various VMs, though I'd like to use ZFS for my NAS needs. TrueNAS Scale seems to be most obvious fit - just not sure the maturity, stability and hardware support is there yet.
