I see people be like "can we use b: for the backup drive" and it just feels wrong.

You probably won't need much for the first phases.
Make sure you are putting outputs into containers, it's better to have a big stock of items than a higher rate. If you need to wait for parts, go out exploring, you'll find the containers half full before you know it. You never know, you might find something to help you out, or something for the MAM.
In general build small plants to produce building resources, then use separate ones for the project parts. A 4/min setup for smart plates only needs ~100 ore a minute, (less than two normals.) That will give you the initial 50 in a short time, and probably the phase 2 amount by the time you have figured out a decent sized coal plant.
As you get on you'll hopefully find more efficient recipes or other ways to increase your production capability.
This is actually a pretty simple to do for an app dev, it's just a window attribute to tell windows to not include (or back out) a window in a screenshot.
