you can save some if you decide to go 16gb ram instead of 32 , i personally wont build pc atm with less then 32gb ram
about the graphics card if you prefer there are other options , check specific games you plan to play and driver support for them if you decide to go with the intel gpu or just get rx 7600 8 gb or rtx 5060 8 gb if you dont mind 8 gb gpu or if you can spend like 430 euro go with rx 9060 xt 16gb gpu
https://de.pcpartpicker.com/list/BFZ48ZYes my idea is 32gb ram with a second slot free.
Same with mother board. Atleast two slots for two memory cards.
About GPU.. not sure tbh... Nvidia looks good to me but dont really care much about getting a very powerfull one since i barely play any videogames anymore.
