I changed and improved my Pc once
It is a good thing that there's no mouse and no ssd because I already have that and I'm satisfied with it and then I could say if all the parts fit together. The 8gb ram will be enough for me and I do not need a monitor for the beginning because I'm Only Minecraft games.
The setup is very neat. As a power supply, I would take the beQuiet Pure Power 500 watts, which is better than the system power. The motherboard is okay, but I would rather take an ATX board like the MSI B450 Tomahawk.
Thanks for your answer but my pain limit 600Euro and then a 90 euro mainboard would be too expensive for me and with 11 years I can't spend 1000 euro for a pc what my parents would not pay
An extra charge of 22 euro is not the world now.
It's not a must, the other B450 board does a purpose as well
