Just finished building my new keyboard.
It has hot swappable switches. I went with the loudest clicky keys on the market: Kaihl Box Jade. Also moved over my custom keycaps from my old keyboard.
I wanted it to be loud but sadly this keyboard has noise dampeners so while the new switches are louder on their own its not as loud once in the keyboard. Either way the soubd is quite unique and feels great.
@freemo a full-sized custom keyboard is quite rare :)
@bonifartius So far I have used cherry blue, cherry green, and now Kaihl box jade... I have all three keyboards near me.
That said it is hard to compare because it seems the sound has more to do with how the frame of the kayboard is built than the keys themselves.
