i would use 3 x 120mm PC fans for this, 2 for extraction, one for intake that moves across the plants as well. you really don't have much room for anything else

2x2x4 you might be able to get away with a 4" inline fan if you mount it all the way at the top, but that's pretty tight. you may want to stick with the PC fans. definitely a space saver.
