Mateyyy

Yet there haven't been any new GPU releases since Intel launched Rocket Lake-S. Could you give some actual examples as to what you mean by "C-O-N-S-T-A-N-T-L-Y featured as a default testing platform"? Ryzen wasn't even a thing to the public 5 years ago.

...do you? Spending $600+ on a platform upgrade for a performance improvement that you won't even notice, unless you constantly have a frame counter up and compare it side by side to what you used to be getting before, doesn't sound like the smartest way to spend your money. At least if you ask me.

It's going to be a pain to delid, and if you actually manage to put it all back together without breaking the chip, you'll only see, at best, a minimal temperature drop. The 3700X is a rather cool running chip anyway, so I really wouldn't bother with LM. A good thermal paste will work perfectly fine (TG Kryonaut/Hydronaut, Arctic MX-4, Noctua NT-H1/H2, etc.), just like the paste that comes preapplied on the stock cooler will. If you're absolutely set on using that liquid metal, you can also use it on top of the IHS; though again, don't expect too notable of a difference over a good thermal paste. Also make sure the cooler you're using has a copper base, as opposed to aluminium, if you do end up using LM. Intel's been using solder since 9th gen, just like AMD has been on all of their Zen CPUs (pretty sure their APUs, or at least older ones, used to have paste instead).

In theory, they should work pretty much exactly the same to the end user - they're both very good Gen3 NVMe drives. That being said, if I recall correctly, several people have recently been reporting issues with the SX8200 Pro, so because of that and ADATA seemingly changing the controllers and NAND like socks in said drive, I would get the WD SN750. And you even get a bonus coffee on the side, since it's €2 cheaper.

...yes

I would only pick the 11700K if the deep learning work you plan on doing does actually benefit from AVX-512. Otherwise, I would much rather take a 10900K/10850K or 3900X/5800X/5900X over the i7.

The cooler looks like what you'd see on a reference GTX 660/660Ti/760. The green PCB is a little out of the ordinary though, so perhaps it's an OEM part, like a 760Ti? Though the best way to find out what it is would obviously be plugging it into a computer and checking what GPU-Z's got to say.

The only board that has a clear advantage when it comes to power delivery over the rest is the B450I Gaming Plus from MSI; the rest are about in the same ballpark. Off the top of my head, the VRM on the Asrock B550 might be a little better than what's on the Gigabyte B450, but considering how anemic its VRM heatsink is, it's not like the slightly better components will make much of a difference in the real world anyway. Realistically, for a 3700X, any of those boards should work, so I wouldn't really worry too much about it. Memory overclocking could be kind of hit or miss on these cheap boards though. Again, the MSI board should be the best in terms of overclocking (likely including memory), but if you can't get over its looks, then I'd just get one of the other boards. Another option would be Gigabyte's A520I AC. It's a very decent board for the money (I'd say it's better than at least the Asrock and Gigabyte B450 boards you mentioned), but the catch with A520 is the finnicky overclocking, as in you'll most likely have to mess with the BCLK to boost your CPU's frequency further. Though it's not like manual overclocking got you a whole lot in the way of extra performance with Zen 2 CPUs anyway.
