Building new PC (GA Included)

I'm not that much of an expert in computer hardware but it seems like a solid build, even if it's slightly outdated. It'll probably last a good 2 years running AAA titles in high res and good FPS but doubt it'll go much further imo. First thing I'd change is the GPU to a more powerful model like 960 but since you've already bought it nothing you can do there. I'd also suggest a 550W or higher PSU. I haven't checked all your parts individually to see how much they need but 450W is barely cutting it(if at all) nowadays, so if you have any plans of replacing/upgrading parts in a year or two without switching out everything it's best to go with the safer option. Might save you some money/trouble later on. The rest either seem alright or I have no clue about those

no point of evo 212, cuz u cant OC ur CPU. stock cooler would be enaugh

Looks fine, the only thing I'd change is the one thing ya can't change which is the GPU xD Instead of the V300 I would recommend the MX100 or MX200 or even the BX100 if any of those models are cheaper for you.

You are going to want to switch out the power supply for a slightly better quality one, and you might want to look at getting a 3.5" hard disk drive instead of a 2.5" one

tier one and tier 2a/2b , tier three you should read the descriptions before looking.

I think you can buy that processor: Intel Core i7-4790K

@edit: You can buy a GTX 780 Ti

Ive heard you only really need more than 8 gigs of RAM if youre editing really long videos, or modding minecraft.

2TB Toshiba 2.5" SATA Hard Drive

IDK if you pulled this from a laptop, or are getting a good deal on it, but typically a 2.5" drive will cost ~20% more than a 3.5". Maybe you are getting this because you think your case wont fit it? Case will fit a couple of 3.5" drives and optical drives.

HyperX 16GB 1600MHz DDR3 2 X 4

Is this 8GB or 16GB? 2x4 would be 2 sticks of 4GB which is a typical kit. 8GB is plenty unless you do something that requires more ram.

Cooler Master Hyper 212 EVO 4 Heatpipes/1x120mm Fan CPU Air Cooler

You dont need this with your CPU, stock cooler is fine.

Corsair Air Series SP120 LED Red High Static Pressure 120mm Fan x 8

You REALLY dont need these at all. Your parts wont put out that much heat to require that many fans. The case should come with suitable fans for airflow.

Id also switch out the MOBO assuming you are sticking with a single GPU, and not going to OC at all. Something like this

 As far as a PSU I agree with above, but I'd suggest a 600w because for most GPUs nowadays a 600w is the minimum. You can check the EVGA website and see what the recommended PSU is for your GPU. (I assume your GPU is an EVGA) Also, always go Corsair when getting a PSU. I've seen a few decent EVGA PSUs too though. 
 Personally I prefer ASUS motherboards over other brands. They tend to be the best out there as far as reliability as far as I've seen.  As an example (Not saying you should go for this) here is the equivalent to your motherboard with ASUS: http://www.newegg.com/Product/Product.aspx?Item=N82E16813132415
 When buying parts always remember it's a gamble. You might get unlucky and get a DOA (Dead on arrival). You might be fine; nobody can say for sure. I go with Newegg when buying parts because they're easy to buy from, they ship things really fast (most of the time), and it's pretty easy to return stuff. Oh, and the constant flow of amazing deals.

Also, combos such as this: http://www.newegg.com/Product/ComboBundleDetails.aspx?ItemList=Combo.1727854 are always good to look out for. (I picked out that combo for myself)

P.S. Is your RAM 16GB or 8GB? You said 16GB, but put 2x4. Considering your current specs I'd say go with 8GB. Idk if you are running a game server and want to dedicate RAM to that or not though.
Oh, and I'd say just a 1TB HDD would be fine Considering you also got an SSD. Just my opinion though.

As you take 16GB 1600MHz DDR3 ram, I'd suggest you taking an other mobo, you could save $50 by taking a non "gaming" one. An $70-80 mobo easily accept, at least, 16GB of ram at 1600MHz. Unless you want to OC your CPU (and as far as I know, the one you've chosen can't be OC anyway), there's no real point getting a $100+ mobo.
All the additional fans seems useless, but I guess those have led inside so if you want to pimp a little bit, do what you like.

Edit: And same thing if you take 8GB. As others mentioned, unless you want to do crazy things, go with 8GB, another $50 bill saved.

My only real concern is the power supply, you can probably do a little better for not much more. That card only requires 300W but if you ever plan on upgrading it in the future you might find yourself a little limited, especially if you opt to turn that GTX750 in to a PhysX card (not really needed, but makes it so an upgrade doesn't make your old card completely useless).

Looks good, but a little overkill on cooling in my opinion. You could just go with CPU cooler + 2 aftermarket fans or stock cooler + 4 aftermarket fans especially since you have such a big case witch already has 1 case fan an good air flow.

The question would be are you planing to upgrade in the future or not.

If you are on a budget, at least the GPU should have been AMD: much better price/performance ratio in the low/middle category.

If you are not using an xxxxK Intel CPU, there is little reason to buy a separate cooler, unless you live in a hot climate. On a similar note, a 4690 would give you more power that the additional cost, it is probably the best CPU of the Intel Core line so far.

16 GB for a low/mid rig is way too much RAM, 8 GB is enough.

That PSU is not so good, get something more of a quality.
