A fan blowing across the chip will do you more good than a small passive heatsink.

I also thought of those small beepers as piezo speakers for the longest time. They're often falsely advertised as such too. I expect that all those intended to be used as PC speakers are in fact moving iron. I think piezo speakers are better suited for higher frequencies than the typical BIOS beeps …

I don't like the idea of rust forming on something that vibrates. Although it's probably harmless, I worry about flecks of iron oxide breaking away from the surface and making its way onto a trace somewhere. Though this is probably VERY unlikely to happen. Again, rust is not conductive. I get that …

The rust on that beeper may just be from poor material and dampness. I wouldn't worry about it. Rust does not spread on copper traces like the battery corrosion does (the reaction between copper and the electrolyte forms copper(II) hydroxide which corrodes copper when in contact with air humidity) …

As far as I can tell it's a hybrid, a clicky membrane keyboard. Personally I wouldn't advertise it as 'mechanical' but rather as 'clicky'. Otoh IBM Model M is basically the same concept (spring over membrane but different 'switch' mechanism) and everyone calls those mechanical.

The switches have an Alps mount as far as I can tell. That'll narrow it down somewhat. Here's a list to browse and compare: https://deskthority.net/wiki/Category:Keyboar … with_Alps_mount

Welcome to the forum!😃 That Pentium Overdrive is really nice but totally wasted on this S7 board. Likewise this pretty nice late S7 board is wasted on a Pentium processor.😄 I recommend getting an ISA sound card for this build too. You found a new rabbit hole to go down.😉

Me and my brother both used one of those (at least I believe it was the exact same model) in our PCs in ca 2004. Both failed before the PCs became obsolete. They may be fine for low power systems like yours but I wouldn't trust them with anything irreplaceable. They were cheap, of relatively simple …

Hard to say becasue I don't have any experience with EX chip set. Only thing I can think is your board doesn't have proper PCI divider even though Voodoo is a AGP card It doesn't use the AGP bus for anything but transfer rates. Anf your PCI bus is running out of spec and causing the voodoo to …

Overclocking stability will often depend on more than just one component. It's not uncommon for individual pieces of hardware to work with an overclock but only in certain combinations. You may find that your V3 will run @83MHz AGP on another board without any issues. It's also possible it doesn't …
