Thinking about the E-2186G....
I'd been rather settled on a 2700x with one of the new boards for a while, but as I'm unlikely to do VM gaming and more likely to do Plex transcoding of UHD in the near future...Intel just gut-punched me with the XEON E-2186G: https://ark.intel.com/products/134855/Intel-Xeon-E-2186G-Processor-12M-Cache-up-to-4_70-GHz
I found a nice server board for that chip: https://www.supermicro.com/products/motherboard/X11/X11SCA-F.cfm
And now I'm wanting a sanity check to make sure
From ASRock Rack. Both Mini-ITX. Both support 8 SATA (4 through OCULink). I can't find them in stock anywhere yet, but, these look like very good Mini-ITX options.
