I decided to go with an E6-1650 v4 / C612 based motherboard as I wanted both ECC memory and a BMC. This required switching from U to RDIMMs, which I typically don't use in a desktop, but there is theoretically a small RAS improvement with RDIMMs. The cost works out to ~$350 more than a E3 system at the same clock rates, and dropping from kaby lake to broadwell. However, it is a jump from 2-4 memory channels, additional DIMM slots, and 2 additional cores.
