Jumped over to the NZXT website to do a little more research. The Source 530 has more 140mm fan options, can even do a 200mm front intake, but ultimately can hold 9 fans. The Phantom 410 can support 8 fans. Both can support your cooler.
If you are worried about air flow specifically, don't go with the H440. I own a H440, I love it. But I keep the ambient temp of my room low and run the 3 front 120mm, rear 140mm and my Kraken x61 280mm cooler running 100%. Its a silence optimized case, not airflow. It has very small intake and exhausts. I read a lot of negative comments about this case getting toasty.
Beyond that, I don't think I can vote between the Source 530 and Phantom 410. I think the Phantom is a little better looking. The Source 530 is a full size case, giving you more space to work with. As for cooling, the Source has a full mesh front and open top, I would guess its the better for airflow. The Phantom does have that side intake though.
