Review on 2pcs PC Motherboard Mini Speaker for Desktop Computer Case; DIY Internal Code Mini Plug Beep Alarm Buzzer by Christopher Hicks

Was a cheap solution. I've followed the advice in other reviews to hot glue the wires to the speaker for extra support as they are very cheap in the way they come together. I could easily see the wires separating without this hack. The noise level is not loud at all; but works if you are having trouble booting your system and need to hear beep codes for troubleshooting. Overall I would say it was worth the price. Bought 2 in case one breaks.
