Raptor drives use a standard molex connector OR SATA connector.
You would need a SATA cable though...Link
If you plan to install Windows on the SATA drive then you need to make sure your SATA drivers for your controller are on a Floppy or CD at the time of install. The windows install proccess should automaticly see the drivers on the floppy/CD.
If you are going to use the Raptor as a second harddrive then no need for the drivers on Floppy/CD as windows will just install the drivers needed if they are not already installed.
