Can you help with computer assembly?

Question

Iron

Good afternoon. A computer will be assembled, completely from scratch, because my 8-year-old computer is already obsolete (you can use it, even ARK: Survival Evolved went, albeit at the minimum, with large animations with lag, but it’s normal).
Motherboard: MSI H270M Bazooka
Processor: Intel Core i5-7400
RAM: Kingston HyperX [HX424C15FBK4/16]
Video card: MSI Geforce GTX 1060 Armor OC 6GB CPU
cooler: CoolerMaster Hyper 212 EVO
Thermal paste: Arctic MX-4
Solid state: Samsung 850 Evo M .2 250GB
Help with choosing a power supply and case. The case is not needed with a game design and not super-duper expensive. Just a normal case and a normal power supply. It is necessary to keep within about 8k of your rubles, it will be less and normal - good. And so in the configuration everything seems to be fine.
Answers to probable questions:
1.SSD for 250GB is enough for me. I have thought over the issues of storing large content. External storage.
2. I take 4 dice of 4 gb each, because I see no reason to put more than 16gb on this system, but there will be a boost in speed due to two-channel. The frequency is 2400 - because the motherboard supports it, the price is the same compared to 2133, but also a mini-boost in speed.
3. I take dies with radiators so that they look with the whole system as a whole, although they are not needed on this RAM. And models without them are cheaper. But still.

Answer 1

Power supply unit ATX 650W CoolerMaster G650M
For the rest of the money, the case is ~ 3000r, which one you like externally. For example: Thermaltake Versa H24 CA-1C1-00M1NN-02 Black
