music machine

Hi All I'm embarking on my first build and in the interest of doing things properly I wanted to ask if you could look over my proposed components and offer any experience or thoughts. The build is almost solely for the purpose of music production, some way between an iMac Pro and Mac Pro...

I've been playing with the idea of making a hackintosh for work(music production) for a while now. My 4 year old macbook pro is starting to slow down on me when I'm working with bigger music files and I'd rather just have a dedicated computer for beat making and music editing and mixing anyway...
