If its not intended for hardcore gaming, you could easily build one for cheap. Don't us Logical increments for a solid base. It works if you are too lazy to research.
Get a Western Digital blue, its ~$50 and works fine and is dependable. You don't need a black. Stock CPU fan is just fine if you don't plan on overclocking or if, again, arent playing a ton of newer games. PSU isnt something you should cheap out on whatsoever. Get a Corsair, EVGA, Cooler Master, or Seagate one and aim for Gold, but bronze rating will do just fine also. Dont need to go over 500w unless you are getting a higher end GPU.
Case is real simple. Find something with decent ratings, good cable management, air flow, and also what you think looks good. Some like simple (Corsair Obsidian or Fractal Design) and some like flashy.
Mobo and CPU: Gonna have to ask someone more experienced there.
GPU is easy. Just tell us what you want to/plan on playing. If you want to play new games at ultra settings, might need something like a 970. plan on playing blockland with shaders, might do well with something a lot cheaper. Plus, while it isn't a GPU, (And it may be different for me because i was so used to crap CPUs) but 4690k has pretty decent integrated graphics, at least better than my old GT 630.
