This workstation is a veteran of both commercial and scientific enterprises.
Asus X99-A motherboard
Intel Xeon E5-2670v3 processor (12 cores)
BONUS a second E5-2670v3 CPU (the motherboard has only one socket)
64 GB ECC DDR4-2133 RAM (all eight sockets occupied)
256 GB NVME Samsung 980 boot drive
Four 3 TB hard disks attached to chipset RAID
NVIDIA Quadro P4000 graphics card (supports CUDA 6.1)
600 Watt power supply

I can install either Windows 10 or Ubuntu Linux; the machine has been used with both operating systems in the past.

I would prefer to sell to a local buyer since it is pretty heavy for shipping.
