> Doesn't Qubes require like 32GB of RAM just to run?

32 GB minimum, but 16 GB recommended.[0] I think that's backwards, so I'd say it's actually 16, not 32 required. But yes, that's more than a typical SBC will have. The Pi 4, for example, has a maximum configuration of 8 GB, but some have modded it to have 16 GB.[1]
