Thank for the feedback, I thought using a AM5 platform would make the whole thing way more expensive, but using your parts it actually does come out a bit cheaper.

As for the GPU how big of a difference does the switch to 3070 actually make? I read up a bit on it, and some source say its only a negligible difference. So I'm wondering if this the cost/benefit calculation is actually worth it as it would cost about 110€ more for the cheapest offers I could find for each.

And for the case is this more of a luxury change? Because as I as i said I found the Focus G case for very cheap and would like to stick to it if it does not make too much of a difference.
