Review on BEYIMEI USB 3.1 Front Type-E Expansion Card PCI-E 2X Interface | USB 3.1 GEN2 10Gbps Type-E 20PIN Expansion Card for Desktop PCs (ASM3142) by Young Toulson

This is as advertised and fits into the slots very easily. I chose this for both Quest Link (although this is now obsolete) and to run some external C-to-C drives I have. The only issue I had was that the cutouts on the included bracket don't line up perfectly, making a single port exceptionally narrow and not able to accommodate many bulkier cables. I don't know if this is a universal problem or just one of the characteristics of my particular board.
