Thanks to BillTech for the great photos and relay research!

I notice a couple of interesting things from the closeup. Here is a portion of the image with annotating rectangles I have added:


The orange annotation shows a trace across the fuse, possible for testing and insufficient to handle the full load. I suspect that trying to run the cube without the fuse would vaporize this trace--with no harm.

The two blue annotations are probably used to indicate is one of the PCI_E connectors is not in place. We have noticed that there is different results with only one connected.

From the relay spec sheet note that the max in-rush current is 40A. That the knock-off-nib is in place is probably an error and probably should be removed.
