I recently rebuilt my PC, and things have changed substantially in recent years. Where we used to fit all the components from the same side of the case, modern cases have the PSU fitted from the reverse side, allowing the cabling to be concealed yet reasonably easy to access. I believe this was intended to make things pretty for the glass-window enthusiast crowd, but it also makes changing the power supply easier. There are also substantially fewer components in general. Things like networking and sound have been on the motherboard for decades, of course - but now 5.25-inch drive bays are also gone, with 3.5-inch bays in decline. And of course with M.2 you might not need any other drives. All of which means there are fewer power cables to plug in than ever before!
