For that amount of lighting and that small of a space, I would get 2 computer fans and run them at a variable speed. You really dont need much cfm for the size box you have. Check it out:

You want to change the air in your box every 3 minutes if you can (for optimal growth) so:

your box is 2x2x4 = 16 cubic feet

16 cubic feet / 3 minutes = 5.3cfm fan

Most computer fans are around 30-80cfm so you should have no problem finding a cheap fan. Just make sure you dont get a VARIABLE fan. I did that and the computer has to change the speed, and by default its on the lowest speed

I would add another little circulating fan to the inside of the door (angled up towards the lights) also to mix up some of that air considering your intake and exhaust are located at the back of the cabinet.
