I've said this before on HN, but no ARM platform is going to catch on for server use, chicken or egg problem, until people can buy a reasonably priced ATX motherboard and CPU by themselves and build a PC with it. The motherboard needs to have the same complement of I/O and bus ports that you can find on a $90 to $120 category x86-64 motherboard.

There is nothing anywhere near the performance of what I can get right now by buying a $110 motherboard from one of the top six Taiwanese motherboard manufacturers, and a $150 Ryzen 3000 series to socket into it.

Linux and *BSD developers are not going to be shelling out $6000 for a 2U rackmount noisy system that's impossible to operate nicely in their home offices.
