I think OP would want a PC that works and is compatible if I'm being honest..

If you are planning to overclock then go with Craigyy_JR's build and like he said add an aftermarket when possible.

Forgot that it was a 3rd gen CPU and that Z97 wouldn't be compatible. I agree with Craigyy_JR's build too.
