A used super micro dual xeon 2680v2 or 2690v2 server with 256 GB of ram is under the $2000 mark. Note the supplier shown may not have stock.

This is as fast as a Intel I9, but much cheaper. What makes is so much cheaper is DDR3 ram is a fraction of the cost of DDR4 ram

Consider also HP ProLiant DL380p G8 server

Dell Precision T761 (workstation)

A guide for CPU choice is here. Do not use AMD. Its much slower for GSB.
