Beginner Resources: RPi4b to learn, then a GSA

Hello there!

I am extremely new to this kind of stuff, and I’m excited to learn! I have recently acquired a Raspberry Pi 4b, which I would like to use to learn how to.. even begin with any of this. My experience with Linux is Ubuntu in 2008, then nothing until setting up my PiHole (I love you PiHole.)

I’ve heard all sorts of things about Docker and stuff. It seems above my head at this point when I’ve looked into it.

What I’d love to do is set up my Pi as a lil NAS. I’m seeing a video from this lovely fellow for setting up OpenMediaVault. Would you folks recommend I follow this verbatim, or should I do more research before doing such a thing? I think I overdid it on my OS card, by snagging a 256GB Extreme Pro (maybe should have gone endurance? I have a USB SSD and some USB HDDs I can use for this lil project.

Anyway, after learning that, I also have a GSA I came across with like 156GB RAM and like ten SAS drives. My mate tells me UNRAID might be the best choice for that. I’m a bit intimidated coming from nothing, so I’d like to play with my Pi first.

I suppose my main question is, for my use-case, does anyone have any resources, video or reading or whatever, that might help this situation? I’ve dug around a bunch but I’m in over my head. I’m good at tech stuff (CFW on my phones when I used Android, which was tough in the G1-G2 days, CFW on my PSP/3DS/Vita back when it wasn’t easy, standard-to-great PC building skillz like most of y’all) but this is a whole ‘nother beast!
