Question Assembled PC Motherboard

[computermonster]

I am assembling a desktop PC for CAD.

I have zeroed down to following configuration.

CPU: i3 8300
RAM: A-DATA Premier DDR4 2400 MHz 16 GB 1 STICK
MOTHERBOARD: ASUS ROG Strix Z370-I Gaming

I neither need overclocking nor hypertheading.

Is my configuration good?

I’m particularly skeptical about which motherboard to use e.g., ASUS ROG Strix Z370-E/F/G/H/I Gaming, or ASUS Prime Z370 P or ASUS ROG MAXIMUS X series perhaps?

Why do you need a Z motherboard if you're not worried about overclocking exactly? What additonal features do you need?
Also get 2x8 rather than 1x16 RAM modules so you can have dual channel config.
What about storage, PSU, case etc?

I chosen Z motherboard because I did not know that it is used when overclocking (OC) is required. Since I do not need OC, please suggest another motherboard that can operate RAM at 2400 MHz without OC.

I do not need any other additional feature. I will only use it for web browsing and medium-level CAD softwares like SolidWorks and SolidEdge.

I chosen 1X16 GB because I might expand RAM to 64 GB. Is A-data OK?

Please suggest which one 4TB hard disk and one 1TB hard disk should I pick. Wd/Seagate/any other manufacturer?

Please suggest which PSU should I pick if I want to use one 4TB hard disk and one 1TB hard disk and I want to upgrade RAM upto 64GB and add graphics card?

Please suggest which case should I pick? Cooler master or any other? Which model?

Thank you.
