I successfully desoldered a speaker from my uninterruptible power supply (UPS).
I ordered another UPS (APC SC420 (hio)) to see if I can do it again!
I wanted a UPS for the Xeon refurb that's coming. I hope to also get one exclusively for the modem and router so that I could keep using wifi during a power interruption. Right now the server and all the networking equipment share a UPS which is probably sensible but the server is going to drain it very quickly.
