I was torn between Prowl and Lazy Moose, with an eye toward the uniqueness of Tiny Purple. I ended up choosing Prowl because of the CPU needing a boost and the fact that it's a workstation as well as a gaming one. I was drawn to Lazy Moose as a true mITX system but I figured that with Sky/Kaby Lake on their way out, there should be a number of still-capable CPUs to slot in there without too much investment. And Tiny Purple is a very interesting beast, from the case layout, to the graphics card. Best of luck all.
