>I guess I was a bit confused. We had used the DE-1 board for school and I might have confused the numbers.
Yeah, not the same thing. Even the DE-10 Standard and DE-10 Nano are quite different

>Is the RAM board nr 2 from the left on the top row?
The one with one rectangular chip? Yes, but there are multiple designs. I believe most modern ones will have two surface mount chips on them like this one, but there are ones with one or four. There were also ones smaller than 128MB but there's little point to that now even if 128 is overkill. The only use people have these days for the smaller ones is if they wanted to forego the analog board for dual-RAM (It's not about adding capacity, it's about adding speed, hence why some if they have an older small ram module lying around would use it for that).

>and it seems that all SNAC controller ports thingies are USB adapters
Vast majority are, a small handful of custom designs use HDMI port, and Multisystem uses it's own port. But they are electronically the same thing even if they use different shaped ports.

>Sure, that's kinda cheap & convenient, but it certainly isn't sturdy.
It's generally recommended to have a very short (as in around 3-6in) USB3 cable for that reason, takes strain off the port. SNAC can be VERY picky if you extend it though so generally there are lists of what cables have been tested to work, and many places that sell MiSTer accessories have guaranteed to work SNAC extension cables.

>Is there a board, like the USB hub, but which instead provides a bunch of controller ports? To make it more console-like.
There are people who made custom MiSTer setups like that, but you would need to provide some sort of way to switch which set are currently connected to the SNAC port. Again, it's not an actual USB port, you can't treat it like one, that includes splitting it through a hub.
