This looks to be some electronics and housing to seat other RPi modules into it:

""" It essentially runs up to four computers interconnected by a network ...

The Turing Pi 2 is equipped with a 1Gbps managed switch, 2x Ethernet ports, 2x SATA3 ports, 4x USB3 ports, DSI and HDMI port, SIM card slot, and two mini PCIe slots ... with a variety of mini PCI-e extension cards. ... """

Price looks to be in the $200 range ("early bird" price estimate at bottom of page).

How are the SATA storage shared between the four computers?

This HN post is the first I'm hearing about it but looking at a video the a reviewer put up, it looks like (at least in an earlier version) there are SATA lines dedicated to particular slots. [0] [1]
