The ROCKPro64 with the PCIe slot has been out for a while.

Does PCIe vs USB3 matter when building a NAS in this case? Your bottleneck is going to be the gigabit network anyway.

PCIe might be good so you can use an used enterprise raid card in JBOD mode. Probably can attach way more drives that way.

how good is it?

The reviews of the rk3399 boards are very positive. It's great bang for the buck with plenty of performance.
