raisner_currency......Think about it ......
"The HHD switch won't work, the HHD is dependent on the motherboard. " I would be asking your friend to explain what they mean ........because if they were correct .......You would have to match up the mobo with the hard drive ...... If for example you had a scuzzi drive ...then the mobo would have to support scuzzi drives ......... Past that systems components operate on a standard voltages ....of 12vdc , 5vdc , 3.3 vdc ...........
Cd drives , DVD drives , hard drives , floppy drives .......
You should be able to use your hard drive ......
Remember ...it's the imput to the power supply that differs ....not the output .
Hope this helps you .
