Looking forward to my second build since 2011. Upgrading from a 3770k 2x6TB enterprise drives raid 10 and 4 hard drives in a uATX case to:
5950x
6x10TB Seagate Exos (already done with old build last week, just moving over)
2x2TB Seagate Firecuda SSDs or Samsung 980s,
AIO 3x120 Cooler
1070 GFX card
128GB Ram.
Asus Crosshair VIII Hero Mobo
Fractal Define 7
I would prefer another uATX build, but the x570 choice is terrible, and no cases to be found for the drive count.
For fun here are the current Raid 10 speeds with the new 10TB Exos drives on a cheap Highpoint 2720 raid card from 10 years ago in a PCIE 2x8 config
