I can't speak to CPU (other than "generally faster is better" and "at least one core per GPU") or RAM (other than "more than 32GB for analyzing big wordlists").
For density (packing a good amount of throughput into a single chassis for the price vs power consumption), the GTX 1080 Tis - the Founders Edition made to OEM spec, not the gaming ones - are popular. FE/reference cards are strongly preferred for cracking.
