  1. Will there be a problem if I attach the usb 2.0 internal cables from my new case to the usb 1.0 header on my motherboard? Its a little older and I've been having a lot of freezing issues after I transfered cases.

    You shouldnt have problems... in theory... but... i recommend to use the right cables in order to avoid damaging an USB device

    any USB 2.0 device is downward compat to USB 1.*

    ONLY buy 2.0 rated cables; there's no physical difference and they work
    both ways. The USB 1.* cables will not however

    that doesn't make any sense, if there is no physical difference, then either cable should work with either version... right?

    Cables have different impedence and electrical characteristics.
    Typical ethernet cables are class CAT5. There are upgrades to the shielding
    which create other classes.

    USB 2.0 cables have better shielding than USB 1*, but have the same connectors on both ends.

    you choose, but now you have something to use or to research further ...

    um... that would be a physical difference, you meant that there are no "visual" differences :knock: lol... but anyways...
