I have a EVGA GTX 660 2GB that's what 12-13 years old and was 2nd hand to me and lives in a tv based sff build and still rocking, bit of either fan bearing noise/coil wine - not sure which haha but it gets used daily and was gifted to me as a temp measure whilst I built a new rig, so probably has had many owners before it! Pretty impressed with that.
Other than that my 2008 mid first gen 'unibody' macbook pro still loves life, as does my 2012 mid mac mini/macbook pro of the same year/hardware...
Some Aiwi speakers from my first ever bought from my own money stereo, must be over nearly 30 years old now...
Creative 2.1 and 5.1 amp/speakers from 20+ years ago still mint/thump/clear...
