These servers have been racked and gone mostly unused since arrival.
The original plan for these servers was scrapped, so they are no longer needed.
They have each been tested and all 4 nodes are fully functional on each server.
I am also working to include rails and power cables with many of the servers as I ship them.
Please let me know if you have any questions, below are the specifications from ASRock.
