So, I'm not a PC person and I really need help. I'm looking for a DESKTOP to work on it. I plan to use it for Photoshop, digital art, and film editing for a youtube channel. It has to have a good memory. My max budget is about 2000 USD. This is the best that I could find. What do you think?

i7 Intel® Core™ i7-9700K 8 core (3,6 GHz) 12 MB

Motherboard: ASUS® TUF Z390-PLUS GAMING: ATX, LGA1151, USB 3.1, SATA 6 GBs - RGB-ready

RAM: DDR4 Corsair VENGEANCE 2400 MHz 32 GB (2 to 16 GB)

Graphics card: NVIDIA GEFORCE GTX 1660 Ti 6 GB – HDMI, DP – GeForce GTX VR Ready!

As for storage, should I get them BOTH built in the PC? I was planning to install Windows in the SSD and use the other for file saving:

HDD SEAGATE BARRACUDA SATA-III 3,5" 2 TB, 6 GB/s, 7200 GIRI/MIN., 256 MB CACHE

Drive SSD M.2SSD PCIe INTEL 660p M.2 NVMe 1 TB (fino a 1800 MB/sR | 1800 MB/sW)
