That's a broadly decent system, but you have a massive problem with upgrades: that power supply is going to limit you a lot. You can't put a strong GPU in that system, and you need a strong GPU for 1440p. The GPU alone could cost £500.
In an ideal world I'd like to upgrade CPU (and cooler), PSU...
The link doesn't work unless you're logged into your account. Can you follow the instructions here and post the full build?
Also, you need to decide now whether we're looking at 1080p or 1440p. It makes a massive difference and the time to decide what to aim for is now!
Great -- this is a much better build. The 7800X3D is decent, but you had the 7900X3D (bigger numbers aren't always better!). The 9800X3D is better still. I hadn't realised how cheap the Samsung SSDs are at the moment: I wouldn't spend more on them, but since they are cheaper than slower...
Great. I don't really think it's a great build. I'd have questions over
CPU
SSD
Hard drive
Power supply
Cooling
I'd be inclined towards the 7800X3D unless you have anything that's massively multithreaded? In games the 7900X3D will perform worse than the 7800X3D and significantly worse than the...
And to be clear in case it's ambiguous from what @SpyderTracks says, any cooler will come with all the hardware to mount it, and normally with thermal paste as well.
You should be able to use most 120mm fans, I'd guess. I've never seen the cooler in person so you should check the fan clips to make sure they'll clip onto your fan.
I wouldn't recommend changing the cooler itself. But if you wanted to, you'd probably have to change the mounting hardware. It's...
It's a solid cooler, and the 9800X3D is not the most demanding chip. I doubt you'll find it any restriction. What you might find is that it's not the quietest or that it fails sooner than other coolers. This is because the fan isn't the best. However, if that does happen, you can just replace...
For £250 it has to be the AOC Q27G3XMN. That would be a great display and fully worthy of a £2k gaming PC.
Then for the PC I'd look at something like this:
Case
CORSAIR 3500X ARGB TEMPERED GLASS MID-TOWER (PCS)
Processor (CPU)
AMD Ryzen 7 9700X Eight Core CPU (3.8GHz-5.5GHz/40MB CACHE/AM5)...
That makes it a much more appealing prospect. What could you spend on a display upgrade? The entry point for reasonable quality 1440p is about £160, but you can spend anywhere from there up to about £800!
It's hard recommending a good PC to go with that monitor. It's really not a good gaming display. It's old and it's slow (as well as being surprisingly small, not that that's necessarily a problem). The build you suggested would be a waste without a monitor upgrade. Would you be open to one?
It's a reasonable PC but I'd recommend a better PC.

In particular:
What's the PC for?
What monitor do you have?
What's the budget?
Ultimately you're not getting much response because this is really tricky! I guess none of your demands are that big, so as long as you can recognise that you are getting a system that is very much a compromise for your needs (well, the video editing and gaming!) then that's OK. It's with that...
That's unfortunate. I hope the 7800 XT will come into stock again. I know it says 1 June as an ETA, but the nature of the graphics card market is such that these things aren't always accurate. Sadly there really isn't anything else in the same broad area of price and performance...
