One rule of thumb for a balanced gamer is to budget 2x the cost of the cpu for the graphics card.
I might suggest that in most games, a I3 like a G4600@3.6 and $88 will game about as well as a I4-7500@3.4 and $190.
Few games will saturate all 4 threads available on either cpu.
2. That will let you spend more on the graphics card like for a GTX1050ti for $130 or GTX1060 for about $200.
Consider the option of initially deferring on the graphics card and using the excellent HD630 graphics.
I think the GTX750ti is only a few tiers stronger than HD630 graphics on tom's hierarchy chart.

3. All the non overclockable processors will come with a stock cooler that will do the job. You can omit the hyper212.
4. Do not buy a single stick of ram. It will operate in slower single channel mode. Particularly bad if you will try integrated graphics.
Do not plan on later adding another 8gb stick. It may not be compatible.
Ram is relatively cheap. If you ever may want 16gb, buy your 2 x 8gb kit up front. 2400 speed is fine.
5. I like the case, bust your budget for a case you love. It will be with you for a long time.
If that is of no importance to you, Silverstone makes some good cheap M-ATX sized cases.
6. 500w is good, it will power a future graphics card as good as a GTX1070.
But, that evga model is tier 4 on this quality list; not one of evga's best:

Buy a tier 1 or 2 unit.
This Seasonic s12II 520w is tier 2 and priced similarly:

I will never again build without a ssd for the "C" drive. It makes everything you do much quicker.
120gb is minimum, it will hold the os and a handful of games.
But, many things default to the "C" drive.
When a SSD nears full, it will lose performance and endurance.
240gb is the recommended minimum.
If you can go 240gb, or 500gb you may never need a hard drive.
You can defer on the hard drive unless you need to store large files such as video's.
It is easy to add a hard drive later.
Samsung EVO is a good choice for performance and reliability.
