I can but the power supply at this point is long gone. However, I can confirm that there are no vent holes for a power supply with a fan. So if the NV has a fanless power supply that may very well be the power supply for this unit. it has 4 mounting points from the looks of it. Also, has anyone attempted to upgrade the RAM in one of these units with any luck?

While the power supply for the NV+ and other legacy 5-drive units is fanless, they have a baffle to deflect air from the main fan through them, and that airflow would be in the wrong direction for that chassis. That supply is basically a re-wired Flex ATX (mini ITX) supply with altered wiring (see ReadyNAS_PSU_pinout ), I think you'd need some sort of support plate for one of them to work.
