I am not familiar with your currency or prices.
But, let me give you some guidelines.
- A balanced gamer will budget 2x the cost of the processor for the graphics card.
- While much is made of the value of many threads, few games can effectively make use of more than 4 threads.
Those games tend to be multiplayer games with many participants.
The single thread performance of the master thread is all important.
For that reason, I like the intel 9th gen processors for gaming.
3. A 2 x 8gb stick of ram is plenty for just gaming. If you are also heavily multitasking consider more.
Ram speed is not very important for Intel processors, more so for ryzen.
4. I will never again build without a ssd for the "C" drive. It makes everything you do much quicker.
120gb is minimum, it will hold the os and a handful of games.
But, many things default to the "C" drive.
When a SSD nears full, it will lose performance and endurance.
240gb is the recommended minimum.
If you can go 240gb, or 500gb you may never need a hard drive.
You can defer on the hard drive unless you need to store large files such as video's.
It is easy to add a hard drive later.
Samsung EVO is a good choice for performance and reliability.
5. For a case, it must, first of all fit your parts. A M-ATX motherboard will fit in an ATX case, but not vice versa.
I have four criteria.
1. The case should have at least two front 120/140mm intakes to provide sufficient cooling.
2. The front intake must have a washable filter to keep your parts clean.
3. There should be 160mm available for a good air cooler.
4. The case should be attractive to you; you will be looking at it for a very long time.
6. Buy only a quality psu.
Here is a chart for sizing:

I have no problem overprovisioning a PSU a bit. Say 20%.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
Look first to Seasonic, they are always of good quality. I like the new focus units.
Here is a quality list:
Credit to @Starelementpokeand @Energycore for helping out with this long-awaited refresh of the old PSU tier list by Aniallation (who previously went several months without logging in), leaving the old list in need of help. This is simply an update of the list that was flawed in creation by the P...

7. Bust your budget for a great monitor. They do not go obsolete and will last you a long time.
LG is very good and will run adaptive sync with a nvidia card. Plan on a displayport connection.
I am very much against liquid cooling when a good air cooler like the noctua NH-D15s will do the job.
My canned rant on liquid cooling:
------------------------start of rant-------------------
You buy a liquid cooler to be able to extract an extra multiplier or two out of your OC.
How much do you really need?
I do not much like all in one liquid coolers when a good air cooler like a Noctua or phanteks can do the job just as well.
A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
in a well ventilated case.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
Past that, A AIO radiator complicates creating a positive pressure filtered cooling setup which can keep your parts clean.
And... I have read too many tales of woe when a liquid cooler leaks.
Google for AIO leaks to see what can happen.
While unlikely, leaks do happen.
I would support an AIO cooler primarily in a space restricted case.
If one puts looks over function, that is a personal thing; not for me though.

Your pc will be quieter, more reliable, and will be cooled equally well with a decent air cooler.
