They can be hard to remove sometimes, especially the 24 pin connector on the motherboard. If you a pressing against the locking tab on the connector and you can clearly see that it's not locking you just have to pull. For the 24 pin you can try gently walking it side to side to get it out.

I have the corsair RMx 750, it works perfectly, https://www.canadacomputers.com/product_info.php?cPath=33_1938&item_id=119735 If you don't need the EVGA Supernova 750w G2 it is a great one as well, PSUs can last a long time across multiple builds. Both ones are A Tier according to that list

Yeah, the motherboard probably has a slot for a NVM to be directly connected to the CPU, in your case with a 3950x it only has 16 pcie lanes available directly from the CPU. Ryzen 5000 series cpus however can do 1x16 and 1x4 at the same time, probably why the slot used the direct cpu lanes. Motherboards now have more nvme slots, some use chipset lanes and others are directly wired to the cpu

You could try spacesniffer or other software like that to visualize the folders on the drive and try to figure out what's taking space

No, the motherboard is fed by the power supply who handles the conversion from alternative current to direct current. Even the power supplies now are almost universal. You wouldn't have any problems since it's the same parts everywhere, motherboards are universal

The ones from the AIO would go on the cpu fan header, the ones from the case any sys fan would do. As for length that would depend on the length of the fan cables, but they usually have somewhat long cables.

Possibly, for sure it is controllable in the BIOS where you will be able to adjust the fan curves, as for in system you would have to check.

From what I saw on your motherboard website you would have enough fan headers on your motherboard for all the 5 if you want to control them all with the motherboard

Your motherboard seems to have 5 fan headers and 1 AIO pump header, depending on the number of fans you plan to put in you case you might need either a Y splitter or a fan hub.

You do not need a TPM for windows 10

It looks insane for the size, the camera body is absolutely tiny. Of course you need attachements to make it work, but it's still minuscule compared to the lens.

Maybe cleaning up the driver with DDU and reinstalling could help. It did fix some issues I had after going from my 1070 to my 3070

I have an older TV that does this as well. I think it's somewhere in the settings there is a setting to control devices via hdmi, if it is somewhere either in the tv or the connected device there is probably a way to turn it off.

I have a G502 hero. You may get unluck and have the switches fail on you and have a double click issue. Had mine replaced by Logitech rather quickly and had no issue with the replacement. The fast double click is a know issue of the 502

Maybe the AI wizardy right now might not be widespread, but in the future a 3080 could last longer in the future with DLSS enabled to keep up with the high framerates. One of the main selling points of dlss is rendering the game at lower resolution and upscaling it. For now AMD's option isn't there, it might come in the future so who knows.
