This listing is tailored for HP ProLiant servers and isn't meant for consumer Windows systems. The seller appears honest, but it's not suitable for regular home or office use.
It seems like a standard PCIe x8 RJ45 adapter, priced similarly to others on eBay above $100. It could be from a seller unfamiliar with the product or simply looking to remove it.
I checked the compatibility details for Windows. It seems there’s no indication that consumer Windows can run it, aside from the mention of HP servers supporting it. The driver information points to Windows Server 2016, which shares the same OS kernel and core code as Windows 10 1607, so there’s no clear reason for consumer versions to face issues.
The price is low because it's not an ordinary PCIe slot. It's a unique HP design that doesn't fit in standard computers.
