A rasb pi apparently works, but if you support classic... you somewhat implicitly support us moving slightly beyond using rasb pi as a necessary lowest common denominator for a full node. You could get into a little fanless intel powered box like this for under $200, including a 4GB ram module and a 120+GB SSD which means you're future proofed for a while:

Oh ok, was unaware that Rasb Pi would not be enough soon. I'll go for something a little bigger. The Gigabyte you are suggesting, according to the Q&A, has issues with Linux driver support. Intel NUC for $20 more might be more compatible.
