I was in a very similar situation as you when I decided to just go with Unraid and build my own. I got a Fractal Design 804 case and was able to put very modest parts in it (i5 6500) and it performs so much better. And now there’s no headaches with drives. I still have my 918+ but it’s only used as a local backup for my unraid. If you’re willing to shift perspective a little it can be very worthwhile. My small opinion…
