RAM is ~70-90 euro if you want something decent, but 2666 is also like 70 euro. Because lol, fuck reason.
SSDs are ~70 for 500gb, and 7200rpm hdds are ~40 euro for 1tb
so 180 for those together
MOBO is some proprietary B550A, which is just a rebadged b450 with a software switch flipped for PCIe gen 4.
So a cheapo b450 is ~70 euro again
PSU is a 400w, they can't even claim 80+ certifications, so.. ~50 euro
Case looks cheap and shit, and you can get cheap and shit cases for ~40 euro
