LED dimmer question

What would be the easiest way to power this 24" 12 led strip ( could I do it with just a POT?)

(Go to specs page)

No.

You need a logic level power FET, like this Usage | RGB LED Strips | Adafruit Learning System

Being a single colour you only need one FET and not three as shown here.

Thanks, but what if I didn't want to use a microcontroller to dim ( even now with the Arduino its better)
What would be the best way with the power transistor?

There are many tutorials and circuit examples on the web about how to use a 555 timer IC with a potentiometer to generate a variable duty cycle pwm pulse to drive a power transistor.

Then why are you posting in an Arduino forum?
