Building a workstation/editing/VM machine from used parts

Hi guys,
found your really nice forum via the youtube channel where you built a workstation from a server motherboard.

I’ve got a question for the pros, I got my hands on a server processor E5-2690 8-Core, 2,9GHz for basically nothing,
but LGA2011 Motherboards are relatively expensive for this chip.

Would a z420 workstation MB work ?
It fits the E5-1620, also LGA2011, so in theory it should, and those are just ~115 instead of >250, but mayne I’m missing something.

I’m also researching what a good value graphics card would be and maybe just putting in a RX460.

thanks for your advice,
