Contacting Super Micro to see if they can donate a SYS-F627G3-F+ server. They helped me out last year with a great motherboard.

Asus never answered my request, it's a shame because the ESC4000 G2 can hold 4 GPU cards and it's less expensive. Not that the Super Micro is more expensive, it hold eight (8) cpus and each node can hold 3 GPUs for a total of 12. A beast of a machine!!!

It has four (4) power supplies.

Just saw this other server which is cheaper and will do the job just fine. 7047GR-TPRF
