I sort of see it a bit differently. PCs now aren't a ton different from PCs in the early to mid 2010s. CPU advancement infamously slowed for most of the 2010s (though somewhat picked up again in the 2020s), increases in RAM trends slowed way, way down as well, and GPUs technically got faster for most of the 2010s, but in the last five years, slowing price/performance of them meant those below the highest tiers saw little practical increase. So for the majority of people, advancement of those slowed down now too.

The big changes I notice were the emerging trends of RGB and tempered glass side panel cases, optical drives being dropped, and SATA being displaced by M2 (although it still exists alongisde it). And I'm not sure I'd call any, or even all of them together, a world of change. We have faster CPUs and GPUs and only twice to four times the RAM, but it's... otherwise still the same.

It's a far smaller difference than how a 1990s PC compared to a 2000s PC, or even how a 2000s PC compared to a 2010s PC (SSD was the big thing there). Things today feel more like an evolution of the decade before it, rather than the revolutions that decades before felt like. But maybe that's just me.

through the 80s and 90s pcs change much more than 2000 to now
atx standard for mobo layout and cards and psu pretty much solidified the designs used today

only things new are pci-e slots which still fit the atx cases of old days, and pci-e and 12vhpwr connectors

you can take an atx case from the mid 90s and build a new pc in it
power, reset buttons, front panel leds for power/hdd and buzzer/speaker are all the same

only issue would be 2.5in ssd mounts, which you can buy or make adapters for, or just double sided tape them anywhere in the case
and cooling, since those cases mainly used the psu and a single 80mm fan for exhaust, and maybe a 80mm fan for intake

as for gpu/card length, many old atx cases support 13+in cards, many old isa cards were that long and even had support brackets in the front for them
ex. this bracket supports the long isa cards, since their max length was defined by atx spec

Given how absolute huge GPUs are getting. They should really start thinking about new configuration for cases where you don't need to sit the GPU on the motherboard itself. Yes, I know, there are supports available. But, it's getting so ridiculous I'd feel more safe if it was done otherwise.

Outside of some rich idiot wanting to post a "look what I did!" video, is there really anyone out there dual-wielding 5090s?

Now I'm picture Neo with twin 5090. The Matrix Re-Reloaded: Bankrupt Edition.
