I bought this case that has a built-in power supply. The power supply says that it is "P4 ready." Does this mean that a Athlon XP motherboard and processor will not work with that power supply? How do I check to see if a processor and motherboard are compatible with a certain power supply? Do the voltages have to much up exactly the same? Or what? Some please explain in detail....

Thanks,
