First pc build: cheap gaming pc. Looking for some feedback!

[sinmaster3000]

Hey everyone first of all Im really sorry in advance if I made an "facepalming" mistakes, I'm quite new to computers in general. I have a budget of just under 1000$ (just for the pc) and I am open for suggestions and opinions. I am trying to build a pc that can run games like smite, dayz, minecraft, Counter strike, and gmod without much lag. Also i would like to know if this case is big enough to fit all these parts as well as have enough air flow within. Thanks!

One side question about my build that I have i noticed that my motherboard has onboard front usb 3.0 header but the case does not. I wouldnt be using the usb header anyways so would this be a huge issue? would the motherboard be affected if i still used it in that case? Thanks again.

Is the SSD card a must have? Because the price exchange has made this build past my budget

Nope. It's optional.
