I'm a fan of the hardkernel.com N2+ computer with eMMC storage. I've only used them for non-desktop work (DNS, DHCP, etc). They're a couple of years old now and it looks like they may have better performing SoCs. They also have x86-64 PCs w/ Intel UHD gfx in the same form factor but the cost is much higher, along with sourcing your own SODIMMs. For a PC, I would jump for the x86-64 system vs. Arm SoCs. There is much less friction with x86 overall.
