They're solid state, nothing is going to vibrate. You're overthinking it =).
I read somewhere on TGO that certain TPI cars (maybe certain year vettes?) got water resistant OBD-I PCMs in the engine bay, but I've never seen one.

OK I have mounted it. Below are the pictures for how it went. I will give an update after I dunno, say 10k miles to see how it is holding up.

I try to mount the ecm to the cab rather than fenders but they tend to be pretty durable. And IME if they exhibit problems related to vibration it's due to a problem which was already present. But make sure the wiring has some room for expansion and flexing. Leave a drop or sag in the harness where it passes from fender to body or fender to engine. Vibration will do more harm to a harness than an ecm.
yeah, that's the first version of the underhood cases that i know of...
first used on the 1227727 ECMs, then the 7727 derivatives in 90(1228708(?), the vette ZR1 PCM and W-body 3800)) and 91(16149396) and 92(92-93 LT1 PCM).... they all look pretty much identical externally.
then in 93, the second underhood style came around, which in 94 the LT1 picked up and was used for a few years until the dual 80 pin OBD2 underhood cases were used everywhere.
