I'm building a three node proxmox ha cluster with kubernetes. I'll be running standard home media server stuff, but also things like pfsense, roon, freepbx, Minecraft, nextcloud, etc. The plan is to put storage over 10gb iscsi. I'm very space constrained, targeting roughly 1 liter devices.

The best option that I have found is the ms-a2. It checks all the boxes except ecc. I would prefer to go with enterprise workstations, but all of the options seem to have one issue or other, primarily lack of support for 10gb (or buggy support for it). Should ecc be a hard requirement? If so, any recommendations for a sff device that supports it and 10gb?

What enterprise workstations do support anything but ECC? Also 10 GBE is old, all server I worked with in the last two years have already 25 GBE cards and above. You cannot configure 10 GB cards anymore. All those workstation work out-of-the-box with PVE and are also SFF, but I suppose you mean something different by that.
