Just to throw my 2c in.
AMD CPUS are so much better bang for buck, obv SSD or the m2 stick to boot OS and HDD for storage. Actually just reading through Scottie's info and that's the way I would go as well. PCpartpicker makes it a quick easy way for compatibility as mentioned earlier.
Not sure where you are based Cupe, but generally, when I lived in Canberra got all my stuff thru PC Case Gear (really competitive prices) and when im in Brissy I generally visit UMart (really competitive prices as well and PCCG ship costs end up more $$). I tend to steer clear of MSY, not for pricing or anything but the experience I have had with them, the sales person was a douche mc'gine-stein so have never shopped there again. Anyways those 2 are my go to for components.
I have had my current build which is only now starting to show its age (i7-4770k) and its has been fine for the last 6 or so years that cost around 2ish K initially to build, and I haven't bother overclocking anything either, but it works fine for the missus and is stable and i think my next build will be along those lines and possibly a gumtree cheapie just for linux distros to play with or just go the whole hog and get a rack mount server and run multiple VMs on it.
Side note, are you comfortable putting the pieces together and building it yourself, and may I ask why you chose scorptec?
