Similar here except it's been since the mid 90s. The last original piece I'm not sure how long but the last since the 90s was the case, a Enlight that was actually rusty, but not up to modern cooling needs. Replaced it in mid pandemic though, same year 2021.

Nice! My last piece was an old 60 gig IDE hard drive. coincidentally also the last component with moving parts (other than fans)
