Quite a nice build I'd say. In terms of value for money, sure, you could save maybe up to €200-300 from discounted BF stuff (only issue with BF discount items is I see a lot of last gen stuff), but in terms of performance your system will do great.
For AI models specifically, 16GB of VRAM could get you a little further than 12GB (just avoid the 4060ti 16GB). It's stretching what's already the most expensive part of the build, so I only recommend it if you plan to lean heavily into training AIs.
