Motherboard standoff screws are machine screws, so how do I fasten those to wood securely? Can I forgo standoffs entirely since wood isn't conductive?
Also, I'm looking at a spare Radeon RX 5600 right now and I can't find any holes that would make suitable mounting points (RX 7900 XTX is what I actually plan to mount).
I see an L-bracket under the PSU so at least that one looks straightforward at least.
Edit: It looks like that PCIe ribbon comes with a mounting bracket attached. Maybe that's how they did it here.
Not sure how wide a variety of sizes there are, but I’d search for “threaded inserts.” You drill the holes and screw the inserts in and that gives you an interface for machine bolts. I’ve only seen them in bigger sizes, but I wouldn’t be surprised if there are some that would fit standoffs.
Yes, that's it! That's the technical term I needed to know. Thank you!
