First time builder needs help with CPU cooler/RAM/case

[MaxVigilante]

Budget (including currency): 2k-2,5k €

Country: Slovakia

Games, programs or workloads that it will be used for: enthusiast gaming/streaming(OBS) at up to 1440/144Hz and amateur video editing/learning (DaVinci Resolve,etc)

Other details:

Hello, I am building a new PC for the very first time and would like to ask experienced builders if everything will be compatible.
Main purpose will be enthusiast gaming/streaming with regular video editing which hopefully will become full time over the years. Price should be around 2k-2,5k € but the part picker has totally different prices because of my country (Slovakia/Europe) so there is that.

I have already bought the CPU and GPU because they were at great price.

Here are my main concerns:

-CPU cooler and RAM clearance: according to this site it will not go well with the chosen RAM unless I move the fan but I am not sure if there will be space for it in chosen case and the last thing I want to do is to return and look for another cooler in the middle of building it since it will be my first time i would like everything to go as smooth as possible

-how much cooling would I need since the base version of the case comes with 2x120mm but I want to go with more expensive version of the same case at local store which changes them for 4x120mm ARGB for only 20$ more

-is it really worth to go DDR5 instead of DDR4 for this build: since DDR5 motherboards in my country are around 100$ more for the same quality and I don't want to downgrade VRM etc. and RAM costs are 20-50$ more depending on specs and the impact doesn't seem that big as far as I know


PS: Do I need to worry about this note from partpicker because I'm not sure I understand it and can someone please explain it if it's a big deal for a first time builder:

Note: The video card PCIe 16-pin power connector adapter is being supplied by three 6+2-pin power connectors. Please ensure that the three 6+2-pin power connectors are not daisy-chained and do not share the same power cable.

Thank you for any suggestions and help.

It should fit. 

Also,  ddr5 definitely is not worth ~150$ extra. Motherboards for ddr4 and ddr5 should cost the same.

Thank you for your response. Please feel free to check it if I made any mistake or overlook something here: Z690 available and this (comparing the same version only 690 vs 790 available)

This is the local shop but I believe you can navigate it just fine.

Would you mind going with german pricing, or do you want to shop local? If so, any online site you can point to?
