Where to get a USB 3.1 "type E" front panel header?

[AJMansfield]

I'm currently in the process of designing a product that will need to have USB type C ports on its panel, and due to physical constraints with the design it would be convenient to use the USB "type E" connector commonly used on computer motherboards for connecting a front panel cable like this one.
However, despite extensive searching, I have been totally unable to find even a single manufacturer or supplier who actually sells these connectors, or even a whiff of a part number I could search.

Here are some images of the connector I'm trying to find, for reference:


The closest I've been able to come are these "IDC 20 pin to A-key 20 pin" adapter boards, so clearly someone is making these connectors available to more than just major motherboard vendors, and there's definitely multiple different designs for such a board on the market (e.g. this this cheaper $11 one is shorter and has different/fewer passives on it).

While a large number of online vendors that sell the front panel cables and adapter boards have taken to calling this a "USB Type E" connector, I haven't been able to find any official provenance for this terminology.
The Official USB-IF Specification (PCMCIA Proposal 279, section 2.1.1) for this connector calls it either a "USB 3.1 Front-Panel Internal Connector" or an "Key-A 20-pin Shielded Header".
The manual for the ROG strix B550-E "gaming" motherboard (selected at random from newegg) calls it a "USB 3.2 Gen 2 Front Panel" connector.
I was also able to find one seller that called the cable end a "USB 3.1 type-c MINI 20 pin Front Panel Header" but this "type-c mini" terminology doesn't appear anywhere else that I've been able to find.

And with all of this, none of these terms have turned up anything remotely close to BOM-able for this connector.
Right now, the best strategy I've been able to come up with if I want to implement this connector is to just buy a bunch of the cheapest "type E" adapter boards I can find and salvage the connectors off of them, but that's a stupid, expensive solution and I hate it.

If anyone has any information at all about this connector, which manufacturers are actually making this connector, where I can buy it, or (the holy grail) a BOM-able part number for the thing, I would be immensely grateful for whatever it is you know.

No, that is not at all what I am trying to get. I am trying to get the surface-mount connector that those cables connect to, so I can use it in my own custom PCB design. (Although if you are able to find the bare cable end-connector without any of the rest of the cable assembly, that would be helpful since the same manufacturer would probably also make the surface-mount connector.)

When the manufacturers themselves nor the official specs don't call them "type E" connectors, it's not surprising you won't find anything useful.

Amy FTW!

Delock has an M2 to USB 3.1 adapter that has a name/logo stamped on the connector, but I can't make it out:

Here's the USB Implementers Forum spec for that connector and front-panel interconnect:
https://www.usb.org/sites/default/files/USB3p1_Front_Panel_CabCon_Implment_Doc_Rev1p1.pdf
Lots of details, but no connector manufacturer or part number listed that I could see.

That says LOTES, who calls them "ICC3.1" in their cables, https://www.lotes.cc/en/product.php?act=list&cid=17&act=list&cid=17 but I can't find the female part.

Talk about Google Fu failing me; I couldn't find these sockets at all.

Thank you so much amyk, now just to see if I'll actually be able to get any of them from them at an anywhere-reasonable price.

why not send an email at Delock   for this item   you may get some answers ??

Success!
WinWin has responded to my inquiry, and will indeed sell me the part - in fact, they're even sending me a free sample.

Although if anyone else decides they also want this connector for something, message me: I may end up having a few extra reels of it in the not-too-distant future.
