USB Front Panel cable

I replaced my mainboard and cpu. The cable from the existing case does not match the mainboard connectors for the front USB connectors. No one seems to sell these independent of the case and it looks to me like trying to rewire is a destructive process (either I destroy the connectors tying to get them out of the plastic block or destroy the plastic block). Anyone know where I can get an “Intel USB” cable or how to rewire the existing cable?
