 It's a good idea but it's to big and overkill for the need.  I will just need a small 12v wall wart and then the voltage rectifiers.  That way it will fit in the housing.  I wouldn't be able to squeeze a computer PS into it.  I can actually probably run my fans off it too as the Arduino and PWM circuitry won't draw alot of current.
