Solved!
Go to SolutionDoes anyone know what this picture is of?
It's described as a T7920 HDD Interposer with a part number of 1HH93
I thought it might be a dual high speed NVME card (the quad is much larger), while the connector nearest the camera looks to be PCIe, the one at the top makes no sense as that doesn't appear on the dual cards I've seen pictures of, so I'm a little stumped. It's the only picture of the item and the person who posted it is away till next week

I don't think it's a PCI in any form: if memory serves PCI cards have a separation between power and signal. Is the UI (User Interface) some form of graphics adapater?

A Google search turned up this description:
ASSY,PWA,CNTRL,M.2,MODULE,V2.
And this forum thread mentions this part as "To install a PCIe 3.0 x4 NVME M.2 style SSD in the Flex Bay area of my Dell Precision Work Tower 7820" as 1 of 4 parts required.

Imho is the pcb inside the 66XHV kit ( flexbay installed ) and that acts as interposer between the U.2 "sata" connector (it's not sata, since it interfaces directly with pci-e lanes) and the removable nvme m.2 caddy

Do you know where it plugs into on the Mainboard perhaps?

I'd read that forum posting thanks, but honestly I'm not sure the person selling it knows themselves what it might be, thus the question if anyone actually recognises it.

Closer end is U.2, the other end looks like OcuLink 4i port (SFF-8611 or SFF-8612, x4 pcie lanes, has similarities with display port connector) used for SAS PCIe/SATA storage devices (which by now is mostly replaced with SlimSAS 8i / SFF-8654 - x8 PCIe lanes)
As for plugging into motherboard - if it doesn't fit anywhere, there's no need to force it, most of this stuff is proprietary and exists only within the narrow scope of MB models. Just because some gismo exists doesn't necessarily mean a whole ecosystem should be built around it, it is normally the opposite.342

I guess for majority of T7920 machine owners - hot-pluggable flexi-bay overkill-engineering functionality has become obsolete these days, instead of expensive cable+adapter+another_adapter with bunch of connectors now everyone just doing it a regular way via direct cable, market has become saturated with all kind of devices to transform standards.
I suspect Dell might be considering another campaign to make all their connectors proprietary and protecting specification from public at all costs.

Here's a video on the nvme flexbay adapters in an T7920. May be of interest.

That board is located inside the housing of a flexbay nvme carrier. The shorter connector on the background side would be connecting to the nvme tray. The longer connector at the foreground is a SFF-8639 connecting to the flexbay backplane (nvme and u.2 only).
I am lazy to take them apart but I attached some pictures of the carrier (same size as 3.5" drive) and the nvme ssd tray. Both with corresponding connector with picture of your inquiry.
