So, I'm building a $900 gaming pc fairly soon, so I needed to know if this build works. Does it?

Looks good although the hyper 212 evo comes with thermal paste and you don't really need the anti-static band all you need to do is touch the metal on your case every once in a while and if you can avoid it build somewhere where your not standing on carpet.
I would highly recommend going for a 990fx board for that CPU, i would say go down just a little to a 7870 if you need to, to grab a gigabyte 990fx ud3.

I added a 990fx board to allow for much more stable overclocking than the board you picked out; I switched out the CPU cooler to an NZXT Respire T40 as it cools almost just as well as the more expensive Havik 140, is quieter than the Hyper 212 Evo, and is 6$ cheaper; changed the case to a Corsair 200R to take advantage of the motherboard's front USB 3.0 header; and finally I changed the PSU to a Seasonic 620w, as it's a tad more efficient (80 Plus Bronze) and is fully modular, allowing you to only use the cables you need.
