Im running a Dual 2690 v4 setup , 30 ish disks , 22 ssd's and 1tb of LRDIMMS in it. ran me about 2200CAD total not including the disks.
usually sits around 260w with a 15-20% load. disks set to spin down (only ssd's active usually).
just parted it together with eBay and local stuff I could find.
it was more of an idea of cost.
100% I would go epyc

48 core epyc 7642 + motherboard. throw in some ram for another 150$ and your on your way to a really good system. tons of expansion.
