In a move that would seem to contradict what we have heard about Intel's new 28-core Xeon W-3175X processor, Newegg currently has it listed as a standalone CPU part for $2977.99.

The official announcement from Intel had only mentioned availability via pre-built workstations from system integrators:

"How You Get It: The Intel Xeon W-3175X processor is available from system integrators that develop purpose-built desktop workstations."

Product page at Newegg.com

Though not available for purchase (yet?), the existence of this product entry in Newegg's system suggests that the DIY community will have access to Intel's most powerful workstation processor after all, and without a markup over the tray price.
