Just to note, IF this makes any difference for you, OP. The unit from Amazon gives you a stand-alone box you can place anywhere handy, but its USB ports are ONLY USB2, and there are two of them.
The Fractal Design panels linked above for you must be mounted in a case front normally, and they include two EACH of USB2 and USB3 ports, with appropriate cables to plug into mobo headers. I would expect those two USB3 ports are of the Gen1 versions - that is, they use the USB3 version of Type A connectors and can move data at up to 5 Gb/s. Even IF your mobo USB3 headers are capable of higher rates, like the Gen2 rate max of 10 Gb/s, these sockets may not achieve that speed. However, Gen1 still is ten times faster than USB2, so those sockets MAY be important to you.
The Fractal Design panel ALSO includes ONE USB3 Type C socket and cable to a mobo header. Such a socket is suitable for use with a mobo header capable of Gen2 performance, and this socket IS capable of those faster data speeds. IF your mobo USB3 headers do not include one for Gen2 performance, the cable from this front Type C socket can still be plugged into a Gen1 capable mobo header.
