FD Terra, 7800X3D, 4080 ProArt Super

Hey! Looks like I won't be the first one building in a Terra. Like other people here, I think this is my first PC build in the last 20 years or so, feedback would be very much appreciated. I went through what feels like hundreds of builds, guides, videos and posts. But I mostly used laptops previously, so there's a bunch of questions.

My goal is to have a compact, good-looking, powerful, reliable and relatively quiet (gaming laptops didn't spoil me with fans being quiet) system which would last me a few years. It should be more or less easy to build and maintain. That's why I tried to choose components which are as popular as possible: there is more info on them in terms of building and troubleshooting. Don't plan any overclocking or other tinkering besides undervolting, turning on EXPO profile for memory (do I even say that right? guess that's what it's called for AMD) and adjusting fan curves. The main use is gaming on a 3440x1440 monitor - Battlefield, Destiny 2, TLoU, Ghost of Tsushima.

What do you think about the components? Should I change anything to better achieve goals mentioned above? I only ordered the Terra so far.

MB: looks like there is no good AM5 ITX MB. I saw reports of some pretty nasty issues for all of them - MSI, Gigabyte, ASRock. Some say that Asus B650E-I can have posting issues with 4080. For some its BIOS is awful, for others it's brilliant. And it can have coil whine. But it seems to be popular.

RAM: Crucial Pro vs G.Skill - price is roughly the same, seems to be safer to go with G.Skill. But Crucial one seems to have those EXPO/XMP profiles both for Intel and AMD, while with G.Skill I need Flare ones for AMD, right? Also would rather go with low profile RAM in case I need to change the cooler, bigger RAM modules don't seem to provide any benefits.

PSU: once again, plan to go with Corsair because it's Platinum rated, extremely popular, that 12VHPWR cable can be bought directly from Corsair. Did I even pick a correct cable? Asus Loki seems to be nice as well though.

CPU cooler: IS55 seems to be the way to go. Plan to swap it's fan for a Noctua one and use the original one from IS55 as a case fan. Looks like it can be done.

Also I saw someone use Noctua A12x15 PWM chromax.black.swap as a case fan - what's the difference compared to a usual Noctua A12x15 PWM 55.44 CFM 120 mm Fan?

CPU contact frame: not sure but seems like it can do some good. At least it can help with thermal paste. Is there any risks to using it?

Lastly, did anyone use Cryosheets, PTM7950 Thermal Pads or something like that? I'm worried that Cryosheets are conductive: in case a piece rips off, it probably can short something. I guess. But the system stays cleaner with it. PTM7950 seem to be interesting too
