The Corsair has better looks, USB 3, and black interior going for it (if you like dark interiors. I don't). But it has limited cable management room behind the MB tray. You have to get all your cables within the 'bubble' in the side panel. The HAF 912 has better cable management and is equally well made. I believe the HAF 912 has more room above the MB at the top of the case if you ever want to add a radiator. I would lean towards the HAF 912. I just recently dug out my old HAF 912 to use in a new FX-8350 build. I had forgotten what a well designed, well made case it was.
