Second, if you did add a Hyper 212, or any tower heatsink for a matter of fact, it would not fit with a GPU unless you make it so the long side of the heatsink is parallel to the GPU (so fans are parallel to the back of the GPU). Terrible idea. I'd switch out the motherboard for a mATX board because the case you chose is a mATX case. Really no benefit of going mITX, as mITX boards usually cost a premium. Bitfenix also states that you can fit coolers up to 160mm high, and I believe the Hyper 212 coolers are 158mm high or less (can't remember, but they're definitely below 160mm).
Third, http://www.overclock.net/t/183810/faq-recommended-power-supplies. Check that list for good power supplies. 620W is probably overkill for a single GTX770. Go onto Anandtech or something and look at the benchmarks for the GTX770, SPECIFICALLY POWER GRAPHS. That will show you the worst case scenario for GPU wattage. Add the worst case scenario GPU wattage and the CPU wattage (the one stated by Intel in this case, such as 84W) to find around how much wattage you need. I'd think 500W is more than enough.
HDD is good, specifically since it's the WD10EZEX as it uses 1TB/platter, so better performance.
GPU I'm concerned about since it uses a non-blower type cooler so it spews hot air in ALL directions which is terrible for air cooling. Standard blower coolers are better airflow wise.
I'll try to throw together a good mATX build. Do you need to overclock?
As for case recommendations for mATX cases, the Silverstone FT03 is pretty nice as far as appearance goes, and is decent in air cooling. The CoolerMaster N200 is awesome (Silencio 352 is an insulated version if you're in another country not in North America). Fractal Design's Arc Mini R2, Define Mini, or the Node 804 are good cases. I don't recommend the Corsair 350D if you're putting something in the 5.25" bay slots unless you're willing to mod or willing to overlook the enormous design flaw. Silverstone's PS07 and TJ08-E are also great cases for airflow.
