    Supermicro M11SDV questions (iommu groups, power connector)

    I think about getting the M11SDV-4C-LN4F for a low power and silent home server. But I still have some things to clarify: First, how good are the iommu groups? Is everything nicely separated? (like the SATA/USB/NMVE Controller and the 4 nics) And the second question: Instead of a 24 pin ATX...
