It should be easy to set up, I've used 3 pin plug from one old fan so I could get easily to +5V, GND and step, it'll come in handy for experiments like these
Connected it and works fine, if a bit too loud (never satisfied
). But when put inside Gotek an inside A500 I guess it will be just right. Tried with 4k6 ohm resistor and it is quieter, but I think I'll stay with 1k resistor to be on the safe side. Only thing I'm not sure of is buzzer's voltage rating. I think motherboard buzzers are 5V rated.
