I bought an N100 for 160 USD including an SSD off of AliExpress. Thats 2x the cost of an rpi4. I benchmarked it and cpu perf is roughly 2x the rpi however i/o was easily 10x without any sdcard or USB shenanigans. Bonus because it's an Intel chip I can use the regular x86-64 os builds instead of some goofy fork. That's very compelling if you don't need a gpio or any of the raspberry pi accessories for your use case.
