I have no experience with rack mounted server builds, but 2 things worry me looking at this.
1. Those two Xeons combined will probably lag behind the rather mainstream Ryzen 7 cpus.
2. Any server hardware is usually loud, since it's meant to be in a separate room. So I'd avoid that for home use.
So, I'd rather build a compact matx box with Ryzen 7 1700 in it.
For example, I've built such a system in Thermaltake V21 case, and they can theoretically even be stacked on top of each other :D
