Colour doesnt matter for the IDE.

To some extent yes, the motherboard does indeed determine what kind of hard drive to install. Most modern motherboards will have SATA ports for the hard drives. The SATA ports are small in size and are usually labeled as SATA1-SATA4 or however many the motherboard has. You can read it right on the board. Older motherboards, however, used to use PATA or IDE hard drives (PATA & IDE are the same thing but with two different names). An IDE port on a motherboard is about 3-4 times the size of a SATA port. The really old boards may not have the IDE port labeled, but most other motherboards will have the letters IDE (or PATA) written next to the IDE port. If you're referring to a motherboard from the last 5-7 years, the chances are that it has SATA ports. The best thing to do is to look at the motherboard.
