SilverStone showed us the ECM22, a neat accessory that provides M.2 slots to machines that lack them. The half-height PCI-Express 3.0 x4 addon card gives you two M.2-22110 (110 mm long) slots with PCI-Express 3.0 x2 wiring. One of the two slots features SATA wiring, which simply relays connection from a SATA port on your motherboard. The card doesn't have any native logic of its own, and as such NVMe booting support will depend on your motherboard BIOS supporting it. It could still come as a boon to setups such as video-editing rigs, in which the creative professional could want as many high-bandwidth storage devices as possible.
