  1. nope, connectors are not same. It will not work like that.

    Edit:

    You can use adapter to connect cases 2.0 ports to motherboards 3.0 ports and get... normal usb2.0 speeds. It's better than nothing.

    Adapters for 3.1 are not quite around yet, at least easily but in that case result would be same. USB is backwards compatible, not forwards so 3.1 supports 3.0 which supports 2.0 but 2.0 will not support 3.0 or 3.1

    The connector is not physically compatible as said. This is to avoid problems caused by the front panel USB and cables not being of sufficient quality to handle the load on faster USB3 devices.

    *However, there are USB3.0 front panel (5.25" and 3.5") addons that connect to your USB3.0 header on the motherboard. See Amazon or elsewhere. I bought a 3.5" and 5.25" both for different computers from ANKER.

    example: https://www.amazon.com/SEDNA-Floppy-Connector-mounting-included/dp/B00PQQQ4S0/ref=sr_1_fkmr1_3?ie=UTF8&qid=1497892555&sr=8-3-fkmr1&keywords=anker+5.25%22+usb3

  3. USB3.0 vs USB3.1:
    This is pretty confusing because if you read the following "USB3.0 is USB3.1 Gen1", so AFAIK most things are USB3.0/USB3.1 Gen1, and Gen2 is mostly devices with the new Type-C connector.

    If you want a Type-C connector you'd need to buy an addon card for that if your motherboard doesn't have one.

    These adapters are backward compatible so if the motherboard had 3.1 you can use this to connect it to usb 3.0 or 2.0 .
    I use them fine with my stuff.

    So this is only useful if you run out of USB3.0 connections but have a spare USB3.1 Type-C connection?

    If so, another option would be to get an addon PCIe (or PCI) card for the motherboard.
