I've been trying to justify that, but it's just too limited for what I want. I basically want to run ZFS, which is a bit RAM hungry, as well as some other processes. So, I basically want 4GB minimum, preferably 8. The latest RPi has 4GB RAM with me option to expand, so it might barely fit the bill for now. I'm not really a fan of the USB interface for driving hard drives, not to mention having to get separate power figured out, and the RPi 4 also runs a little hot. So I have been looking at other options, like the Nano Pi m4 and the RockPro64, both of which have SATA expansion options. However, to get everything I'll need, it'll cost $100+ and only be a short term solution anyway. So, I've decided to just get another stick of RAM for my old desktop (runs 4GB right now) and just eat the extra memory usage.
