Uhh, plenty of people still use them (it’s still the default for many gaming monitors), and for 32:9 displays you absolutely need it curved or it’s basically unusable. I don’t think they’re going away any time soon, because they’re not a “trend”.
The thing that I wish would go away is oversized graphics cards that take up 3 or more slots. There needs to be more options for liquid cooling that doesn’t require modifying the card.
Ya acrylic side cases where a trend, maybe 3D monitors but everything else in there was just specific technology that has been replaced by better technology…
I remember the first full build I did. All of my fans had LEDs, the case had LEDs. The first time I tried to play on it in the dark basement the SU was blinding. I disconnected all of the case LEDs, and replaced my fans for plain black ones.
