RAM
Looks like in general, 4x16GB (64GB) runs around $550, so we're looking at a touch over $2k for 256GB 1 32GB module runs around $500, so for the same price, we could get 128GB, but have 12 free slots instead.
1 64GB module is nearly the same price as the 32: $600. (1TB = 16x64GB of RAM = just shy of $10k)
CPU
These run about $500. Newegg doesn't sell any, but Amazon has them
