Lots of users mucked around with arm boards years ago untill most realised this wasn't something Arm was interested in with no drivers and those that existed not optimized for performance. It was all a hack with open source developers being kicked like footballs from ARM to SOC vendors and back. Interest waned.
A NUC can be had for about $120 that sips power and has full hardware support for storage, pcie, graphics and is seamlessly compatible with the entire software ecosystem.
ARM is more comfortable with vendors ie soc, routers, nas vendors than supporting an open platform with access to optimized drivers and off the shelf parts. Thus the entire mobile ecosystem is closed and tightly controlled. Even early devboard makers like Odroid have moved to an Intel platform for their latest N1 dev board.
I've come to the conclusion that neither ARM nor the actual SoC vendors are interested in desktop or server hardware. The majority have canceled their server projects or sold them off.
