if you know how to buy from TaoBao and knows how to build PC from parts - you can get way cheaper.

Also - my PC spec is almost similar to what you are planning to buy, I "had to" rebuild a new PC from my old Intel i7-6700 system to keep up with windows 11.

My PC spec now -

AMD Ryzen 5600 + stock fan
Gigabyte Aorus B550m
64GB DDR4 Corsairs (16gbx4) - reused from old system
Gigabyte RTX4070
1TB NVME Patriot - reused
2TB HDD Seagate - reused
CoolerMaster v850 Gold - reused

old casing - cooler master
