I finally got the MP40 yesterday with no change, so it's the cabinet/ power supply unfortunately.

I have one coming shipped 2 day.

I powered it up empty and I could hear the power supply but no fans moving, even after spinning them.

The sides of the rack they have are solid sheet metal with not much wiggle room on the sides, I wonder if the cabinet overheated?

There was a 7200S in the same spot for years but different fan positions.
