$42k and a toy CPU at that. Threadripper or EPIC if it must be AMD camp, although I'd rather it weren't (_always_ some random issues on linux). TBH, if I were buying workstation at such prices, I'd probably first take a look at what HP has (since their cooling and immunity to dust is unprecedented), and then probably BOXX and Puget. For DIY there's always supermicro at such levels.
