The motherboard does not connect the power supply to the peripherals. The power is supplied directly to most peripherals such as HDDs and CD drives by cables from the power supply. Some special expansion cards, such as network cards, get enough power from the motherboard through the PCI slot to function.

Otherwise as long as the voltage and amps are the same it doesn't really matter. If you try to plug it into both you will double the power of the fan and very likely fry the fan.
Case: minitowers:compact cases,low-profile cases or slimline cases. Power supply: ATX power supply
