This isn't a typical server board, just FYI. Kind of a special case where a low power x86 solution is desired. Mini-ITX is not a 'server' standard. Designed more for small business I imagine.
In larger enterprises the typical boards would have Xeon or Opteron (And now Epyc) processors that are replaceable, and intended for U type rack mount applications. Or they will be Sparc, PowerPC, etc CPUs with hundreds of cores that run Unix. Windows is somewhat uncommon in the hosted application space. (Though it is what I spend most of my time on, but many manufacturing, engineering, and science applications tend to be made for Windows)
Finance, payroll, trade, banking, etc tend to only have Windows machines as clients, thoseroots can be traced back to mainframes. Graphics is usually PC, but that is more a recent thing as those used to be primarily done on proprietary platforms, usually RISC processors from Motorola and the like.
