Perfect!
The first computer I received with a defect, the LDLC advisor directly proposed to exchange it for a new one, while warning me that it would take more than a week and... I received the new one in less than a week. The LDLC after sales service is still one of the best, honestly.
Nothing to report, I haven't tested it in game yet, only on Photoshop, Illustrator and InDesign, so until then I'm really happy with the PC. I'm really happy with the PC so far, but beware that it's only compatible with Windows 11, because there are a lot of bugs with Windows 10 (the screen doesn't come back on when I wake up from sleep and when I reboot).
The RTX 4060 really changes the game in terms of graphics rendering (compared to my old PC which was on a GTX 1660 Ti). I'm not sure how it's going to fare in the long run, and I hope it does better than my old one (msi GL65 Leopard) did in three years.
