@pete-s said in ARM Desktop I Finally Want:

Add $30 for 4GB of memory and you're at the same price as the board you mentioned but with 2-3 times the performance of the rockchip. The J3455 is an older NUC so it can only take 8GB RAM.

Well that's at least $160 vs. $129. But a bigger deal is power consumption, I think. I'd like to see the numbers, but I bet that the RC is dramatically lower.
