On occasion i piece together, or upgrade, desktop pc hardware. It is truly amazing how all the parts are pretty much just horrible through-and-through. Things like: Screws of different specifications; Power cables that go the wrong way (I guess some expect you to run them through the back of the motherboard tray and then come down from the top of the case, to be all cool and tidy, dunno); Power connectors that aren't symmetric (ie all of them) and the keyways are hard to see and don't really work just by feel; Power cables that have wiggly pins (ie molex); AM4 socket back brackets that fall completely off and down into the back side of the case when you are removing the cooler to redo the thermal paste; Mounting for various data drives (hdd, dvd, ssd, laptop hdd, etc.) being a nightmare of incompatibly placed screw holes, and easily lost or broken drive rails/caddies; all the stupid age-old fiddly bits of a zillion different connector types like the bloody front panel pinouts; pc cases that aren't perfectly flat on top because it just looks cooler i guess; etc. ad nauseam. Sure that's why people "just buy a dell" but a lot of these things are just painfully obviously bad physical design stuff that i feel like you'd have to explicitly go out of your way and spend R&D $$$ on to make it as bad as they make it. And this is from name brands in all the parts, not just some random producer nobody has ever heard of before.
