A bit of a shot in the dark:
I'm trying to crack open the power supply of my Sun Ultra 1 (a Sony APS-72) and I can't for the life of me figure out a way to do so without bending and potentially damaging it.
On the first picture, the blue arrow represents the way it's supposed to open once the 2 chassis screws are removed. However, the part circled in red prevents that motion.
Would anyone know how to get past this without breakage?
