There are a few wiring conventions for the USB headers, specifically in respect to Data - and Data + being swapped, your case should have either legends on the connectors or reference to colours in the build sheet that came with it. Refer to the mainboard documentation and match them up.
If documentation is not to hand then you can experiment with Data - and Data + but make sure that Supply + and - are not swapped (all conventions I know about have them in the same place anyway) or that Supply is put on Data pins and vice versa.
USB spec says that all pins should be able to tolerate 5V without damage, but you should not count on that being the case for every device/board available.
