Laptop for animation: 1080 resolution / 60sec lenght

Hi

Am a user of Adobe Animate for a long time and thinking to learn After Effects .
I had read again and again articles about building (like PUGET Systems), and now I have more doubts than before 🙂 .
There is a good deal on a: MSI GL65 Leopard 10SDR (i7-10750H/8GB/512GB/GeForce GTX 1660 Ti/FHD 144Hz, in which I will upgrade RAM to 16GB but it isn't upgradeable to a second SSD, just 2.5 HDD, so am worried that might be too slow.

All the projects I work on is 1080 / 60sec in length, 10-20 layers of moving images & vector.

Thanks for any advice you can offer.
