Most guides I've seen are very incomplete or don't list specific models of everything -- or if they do, it's only for a specific point release.
At a glance do you think this hardware would be good for now and future versions of El Cap + Sierra when it eventually ships?
I built this back in 2014:

(Mic and overall audio performance is very important to me due to recording courses, podcasts, etc.)
