I would have gone for a 500gb sdd personally.
Definitely get 16gb of ram.
I have previously run an RX5600xt and a 2600x on that 450w Corsair unit and it worked fine, and your system will draw less than mine did but if you can afford it get the sea sonic unit. 
Both of those cases will be decent but I would personally pick the Corsair for Ease of building and the included fans as well as aesthetics

Budget (including currency): £1700
Country: UK
Games, programs or workloads that it will be used for: AAA Gaming at 1440p, CAD, Photoshop.
Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): I am looking for a £1700 gaming setup for Playing AAA titles at 1440p gaming at highest settings. The budget includes a mouse, keyboard, headset and monitor. This is the best config I could come up with. If you have any ideas about how to make it any better please let me know.

I have now decided to return the 2060 an get something cheap until I can get the 3060

If you have an existing drive you should be able to install it no problem.

Thanks. I enabled XMP and that auto set the voltage to 1.35 and its all working now.

If you don't want to overclock you can save £30 and use the stock cooler included with the CPU.
I would also change your graphics card to a RTX 2060 or RX5700 for around £10-20 more as you will get much better performance.

I'll switch the motherboard back.
The keyboard I've got there also comes with a g305 mouse.
Does this motherboard have better performance:

What FPS do you think this system would get in Battlefield V?

This is for 1080p gaming on titles such as battlefield V and photo editing. £700 budget.
