I hadn't built my own machine in years and wanted to build something that would last me a few years.
Nominally built as a Photoshop editing machine it will probably see more hours as a dev / research box.
Cases have changed dramatically since my last build. The case I used (Corsair Spec-06) is pretty slick and I liked the cable routing I was able to do - made the finished product look clean.
TIL: Rough in the cable runs (esp power) before mounting everything.
The CPU idle temp is correct; I haven't bothered with the other temps yet (and may never do it).
