Yes, though as you say the PCIe version has its advantage. And yes, they all can, but your scenario is definitely one where X870E, which is normally excessive for a gaming PC, totally makes sense, and it's what I'd choose in your shoes.
You can keep the Elgato 4K60 Pro and get the full bandwidth if you go for an X670E board. Either the Crosshair or the Aorus would be fine – the Aorus is a lot cheaper.
I guess it depends on why you need 8TB of storage. If it's for game capture, a hard drive would be a better bet. If it's for storing games, I guess it might make sense to go for the massive drive if you really need it. If it's for video editing, the hard drive might also be an option, or you may...
Looking at the manual for that motherboard, it appears that the PCIe slots are independent, though both are affected by M.2 cards. If the second M.2 slot is filled, the top PCIe slot is x8, otherwise it's x16. If the third M.2 slot is filled, the PCIe slot seems to be disabled. The first and...
What monitor will you be using? (Make and model, or resolution and refresh rate.) What's the budget?
Basically you can get a lot more for this amount of money by spending it more wisely.
I'm not an expert on power supplies or indeed electronics of any kind, but this seems like the noise a relay makes when power is turned on.
Do you turn your power supply off every time you turn the computer off?! That's very thorough if so!
PC and monitor should be a good match. That's how you get value. If you're spending £2800 on a PC but have a terrible £150 display, you're wasting money and should divert some of that budget to a new monitor.
But also you don't want a PC that's underpowered for the display as that's also a waste.
I mean they don't fail with the frequency they used to, and often firmware will detect incoming failure. But yes, they are still prone to complete failure. But in any case, You Must Have Proper Backups.
As @Ekans2011 says, £1200 is quite tight for a gaming PC. You can get something in the region of £1200, but do be aware that it will be limited in performance and I would not expect it to perform as well as a games console. But if you're on an HD TV (which presumably is 60Hz and probably...
No, don't lessen the speed of the RAM. 6000MHz is where Ryzen 7000 performs at its best, though I doubt the timings here are top-end, unfortunately.
It's similar in performance to the 4070, probably a little ahead (if you look at reviews, they're from release day: the 7800 XT has got a little...
Here's what I'd do with your money. The compromises here are (a) CPU power, (b) a "meh" cooler, and (c) a graphics card that isn't going to be great in VR.

You've downgraded the power supply. I would not do that. Principally because you want the headroom of extra capacity, but even more because the RM version is old and the RMe version (the 750W one) is new and much superior. It is worth a few extra quid.
The storage drive is fine. As for your...
Well, at this budget everything is a compromise. That doesn't mean it's bad, but it means there are inevitably compromises. One of them will be performance right now, versus long-term upgradability and indeed support.
Other compromises you are making are:
choosing the slower GDDR6 version of...
