My new favorite subreddit is r/techsupportgore, where people who fix computers post the nightmare scenarios they find themselves in. It’s not always the grand-guignol horror of Playstation 4 cockroach farms or, as pictured, loaves of solidly-baked dust. Some of them are subtle problems that can take a while to spot or which might even be invisible to nontechnical folk. Sometimes, the name is literal.
