I'd test the stock fan placements first since it looks like the C70 comes bundled with some pretty good cooling. I'd definitely do a bit of experimentation before dropping money. The NH-D14 should fit fine. I'd use it in the usual horizontal configuratiion. That said, I'd rather go with the Phanteks PH-TC14PE. It doesn't cost much more, but performs slightly better and looks cooler if you get it in black or something.
Nice on the RAM and the SSD. Any idea what you're getting? Please say Samsung 840 Pro LOL.... =)
