Thanks! In case you're interested in building a ThreadRipper Pro WX-based system like mine, then AMD apparently starts selling the CPUs independently from March 2021 onwards:
Previously you could only get this CPU when buying the Lenovo ThinkStation P620 machine. I'm pretty happy with Lenovo Thinkstations though (I bought a P920 with dual Xeons 2.5 years ago)
My only quibble with that board is that I worry about how easily replaced the fan on the chipset is. In my experience that exact type of fan will inevitably fail in a moderately dusty environment... And it doesn't look like anything you could screw on/off from the common industry standard sizes of 40mm or 60mm 12VDC fans that come in various thicknesses.
Fortunately you can often swap the complete heatsink and fan combo on the chipset with a different one. If the mounting method is strange one can use thermal epoxy or thermal adhesive tape.
