Looking for a bracket adapter (Flex-ATX to half-height PCIe)

[Machupo]

Anyone know of a place to source a piece of metal that will mount in a Flex-ATX PSU bracket (roughly 40mm X 70mm) and have the appropriate mount for a half-height PCIe card?

I have a 1U edge device build that I am shifting from Flex to a pico-PSU and want to use the space to add in a 4-port PoE+ nic (no expansion slot exists in the chassis, because it is 1U)

Disregard, ended up going with a 2U dual-ITX chassis. Besides, bridging << switching, lol.

Now have my edge device, NAS, and cable modem all in one silent chassis
