Gotta love the folks trying to sell you on a different build instead of answering your question, lol.

Regarding the case - looks are subjective. I personally like things to be minimal and a little understated. I like the bequiet! Dark Base Pro 900. for something that's close to silent.

If you want a tempered glass side panel I like the NZXT H710 (or H510 if you want something smakller) cases quite a lot. They are simple, but quite functional and with the right fan setup they can really do a decent job with cooling.

The 10850k is almost exactly the same as the 10900k but it's cheaper.

The Viper Steel modules are too tall to fit under the outer NH-D15 fan in its normal position. I'd suggest using low profile modules like https://uk.pcpartpicker.com/product/VNJtt6/corsair-16-gb-2-x-8-gb-ddr4-3600-memory-cmk16gx4m2d3600c18.

Here's my recommendation. You could get 32 GB of ram too, depends on what you're doing with the PC.

Is this a gaming centric build I assume?
 
Id go for faster ram. 3600 CL16 would be a fantastic option. 3200 is a bit on the slow side. 

We should talk about the CPU choice before these two, it's harder to justify Intel than Nvidia at this point. Should still wait for Ryzen 5000 benchmarks tho
 
RAM isn't overkill for capacity, for a high end rig 32GB makes sense as long as it doesnt lead to cutting corners elsewhere. The frequency and timings tho are quite weak for a high end system. 3600MHz 18-22-22-42 should be the bare minimum for anything above US$1500. At 2 grand of british money for everything inside the case there should be 4000MHz memory. Faster memory helps with frame rates as well.
 
Should wait for the AMD card, even if you dont end up buying one from them. AMD should have a competitor for the 3080 (not so much 3090 tho) that can help drop prices and increase supply (since there's now two options)
 
Also overclocking headroom on the 10900k is limited with an air cooler, that 300w class CPU needs better cooling than that.

Someone I asked on another forum made some changes to cut costs but kept the power there, tell me your thoughts :
