Looks like a winner at least as to RAM _relative to_ any of the RPi SoCs.

2GB RAM model $65
4GB RAM model $95

(Doesn't include optional heat sink, or case, or 12V/5A power adapter.
The heat sink would be highly recommended.)

And the other win is the pair of PCIe sockets, such that you can
potentially use real mass storage, e.g., SATA-connected SSDs or hard
drives.  _Or_ you can follow the path of least resistance and buy either
a micro SD card or an eMMC flash module.

As to the ARM-family CPU:  I see mention of Cortex-A72 and Cortex-A53,
inside a Rockchip RK3399 SoC (System on Chip).

One thing to bear in mind is that _all_ ARM systems so far are
special-snowflake hardware, in the sense that, e.g., every single ARM
system requires a special kernel constructed using out-of-tree
patchsets.  Standard kernel.org code doesn't run on them.

The PCI-e is on the 24 pin header.  I don't see any info yet on how to interface with that.  
But the manufacturer has made a prototype SATA hat that connects to that header.

I am wondering if you could just solder a nvme to those pins instead.  Though that SATA 
hat would maybe make this into a small NAS.  

Another issue is that it is powered via the USB-C port but it is not compliant (i.e. it does not
communicate power requirements to the usb c power supply.)
