Meh. I'd rather get one of the dual-xeon setups I listed. For the same price you're getting a quarter of the ram, half the processing power, a quarter of the CPU cache. It will do better in single-threaded apps, so it all depends on the tasks you're facing. I do lots of 3D rendering, so I'd pick more cores, RAM and cache.
The other advantages of your setup are power efficiency and NVMe.
Oh, and btw, you will save yourself a ton of money if you just bid on the components on eBay. Take, for instance the CPU. You're going to pay $325 for it. Now check how much they auction for:
