I'd reflow the back of the PSU PCB, might be a dry joint. A can of electronic freezer spray might help you diagnose here as appears heat related; also check diodes, and exercise/clean the voltage potentiometer to rule this out as well.
Cap goo on Classic analogue boards is like honey, it leaks down and dries out causing all sorts of damage along the way. It will need a deep clean before and after recapping Also search here for other likely components you'll need to replace: the optoisolator, and TDA4605 on first thought.

Check the service manual, it recommend the best way to lift the panel and confirming needs more force than most plastic Apple parts. Once you get it off the repeated replacement is easier.
Hi Trash,
I’ve got a TAM and 5500. Both have had various PCI cards but find a generic USB card in there for both most of the time. Most recently the TAM has a Sonnet Tango 1.0, which will stay but I do find FW on it problematic regardless of the recent OF patch put out there.
The others cards...
Hi,
Great fun but I suspect you will need to try an older Mac OS, and fresh install of DOS/Windows in new partitions - they could be corrupted. Mac OS 8.1 does not play particularly nicely with PC Setup 2.17. See also thread here on it...
You can use/make a key remover pulling directly up but on the keys with stabilisers don't pull as hard, lift up then check the wire has been fully unclipped. Keyboard is the worst to get back on as reassembly; do it first and note the orientation of the key!
Also check the continuity and quality of the harness going to the motherboard; have come across some where the corrosion has wicked through some of the wiring
I'm in Melbourne but don't have time right now, I'd recommend you learn to DIY as with any SE/30 it's not just the motherboard, you're also looking to the PSU analogue board and likely floppy/HD will need attention.
You could probably bend that back in position pushing it through a rod or something, pliers to push back and reset. It's not a particularly imperative part with broad tolerance to slide back either the shutter or position the floppy housing to push down when activated by a floppy.
