At least those would be useful for the people wanting them. No need for an AIO if a 4090 cooler was somehow compatible with the mounting/VRM layout.
Scammers have already returned 4090's to retailers with just the cooler inside for weight, and just kept the GPU. They have no need to even attach some other card to it.
It's going to be nasty if these things flood the second-hand market in the future. Sustained high temperature operation combined with likely substandard power delivery with questionable reballing quality. What a perfect recipe.
As Admiral Cartright said definitely a SMD capacitor.
Problem is there's so many unpopulated points on that board that you would have to spend an hour eyeballing them to find the one it came from. The good news is he's right, the board will almost certainly run fine without it.
But try to be more careful with your hardware, a simple slip of a screwdriver can cause that with those small SMDs, and you really don't want to chance fate with SMDs on say a GPU...
There's been a gradual shifting away from really old designs on equally old and/or 'hardened' process nodes, simply due to the age, cost, and performance gap. Also older chips didn't have the redundancy, self-correcting, and failover capabilities of modern processors, so some of the perceived risk from using much more modern nodes and chip designs is being offset by the redundancy modern chips can provide.
No, backlight zones isn't any sort of thing to make a standard out of so I don't see that happening. Adding zones adds cost, and OLEDs are rapidly coming down in price so I think FALD monitors above 1152 are going to continue to be an expensive rarity. Sellers aren't going to want to make them and a year later risk having OLED prices undercut what it cost the vendors to manufacture them.
The InnoCN 32M2V has 1152 zones and is down to $600, same panel as the ASUS PG32UQX. The zones are more like postage stamps, not perfect squares.
Micro-LED sounds amazing, but I've not seen anyone say it won't require the same local dimming zone technology. If it's too costly to make every mini-LED directly controllable then it's certainly too costly to do the same with micro-LEDs I would imagine.
