I've seen Linus Tech Tips do a video on 4k $1000 PC, but I wanted to see if I could get something better equipped for 4k than his rig. 
I think I have succeeded, here is what I got:

So, can you technically build a true 4k gaming PC with $1000 and still play at goods settings. YES!
But what are the disadvantages:
1. Esthetics goes out the window, so if you have no desire for esthetics then this is a good build for you.
2. Not a lot of features, especially from a H81 motherboard. No modular PSU, and regular speed RAM.
(Update...) 3. No OS. I usually don't put OSes in most of my builds because they are targeted towards enthusiasts that already have a OS. However, most non computer techy people don't have a OS sitting around, so this will be a major disadvantage for you. Adding windows 8/10 will be around $100.
Bottom line, if you just want to play 4k at good settings and that's it. Then this build is for you!
