Would this adapter work inside a Windows Desktop PC?

Is this adapter with mini PciExpress Host Interface only for laptops or would it ALSO work inside a Windows Desktop computer?

My motherboard is an Asus Z87 Sabertooth with 3 Mini PCI Express free slots

Ive seen both opinions that it is ONLY for laptops and Intel Pages where  it calls it a Desktop adapter albeit with different part numbers. They do not have this number listed anywhere, so i get the distinct feeling that Intel has it listed under another Model number

Could anyone be of help to clarify this for Me. My Desktop PC runs Windows 7 Home 64-bit.

Thank you
