So I didn't build this but did pick it up today. Dell R620 with 2xE5-2650v2 (8c, 16t) and 128GB of memory. Don't have any drives for it yet but probably gonna do a 128gb ssd I had laying around from my laptop, then 3x~1TB SSDs for vm storage in some sort of raid configuration. The main things i'll be running is a jellyfin server, home assistant, and a few websites i'm currently hosting on a mac mini. I'm sure i'll find some more stuff to host down the road as well.
I have a very similar setup from Boxx Workstations for 3D rendering. And another couple of workstations with a similar setup, but just one processor each for actual production work. I have yet to max out my RAM haha.
