Yes, a MOBO IO shield is quite significant for protecting your setup.

It might stabilize the motherboard to the chassis, but it already does so via screws and standoffs, plus power cables. You could also operate your PC without grounding—it’s mainly about safety rather than performance.
Thanks for all the helpful responses. I’ve been working on fixing this old computer since I got it, and some of my questions were tough to find answers for. Really grateful you took the time to reply.
Found a thought-provoking remark on Reddit: it might suggest that an OEM motherboard built for a particular setup could have inferior EFI compared to retail units, since it only needs to meet FCC standards as a whole. Running without a case seems risky, but missing an IO shield probably isn’t a big concern. I think modern PCs are likely better equipped too, as they operate at higher speeds and radio interference tends to be limited in range now. Also, coil issues are more bothersome these days because higher frequencies make them easier to detect.
