Need Help Choosing Parts

breathControlled

Hi all!
Newcomer here, first time ever PC builder, switching from decades of Mac. Somewhat frustrating years, some of them!
I am a professional musician, entry level music/audio recording, VSTi and DAW user. I will not be doing video, am going with Intel, so don't need a GPU. I've been advised to aim for stability over speed. 
I put this parts list together and am looking for some advice. Especially as to case. I've heard glass tempered is not great for maximum cooling.  My 2010 Mac is overheating even with with my entry level recording and editing demands.

Thanks for any pointers!

I see that you ask for budget info. I want to keep it under !000. 
Thanks

...and I won't need a sound card because I use an external hardware audio interface
