PC with €500 Bugdet (Without GPU)

I would like to build a PC in a little while and I would like to know if these components are good with a budget of around €500 to start it. Ryzen 5 5600G (iGPU: Vega 7) Motherboard B450 32GB RAM (3200) 1TB (M.2 NVMe) 650 Watt (idk if they are enough for the future GPU that I will buy) SMALL CASE and the vent (idk if they are good but I will find out) the use is for medium gaming as you can see I don't have a very high budget but I think it should be good, your opinions?
