I have ZBOX MI571 with an i7-6700T and 16GB (SODIMM) RAM laying unused. And I want to make a personal backup/archive server, for which I think TrueNas will work best.

The box has more than enough computational power for running TrueNas. But as far as I could find it has only one SATA and one M.2 SATA port, so not enough to have a boot-pool and a redundant storage-pool. And it doesn’t have any spare PCIe ports.

So I’m wondering what’s my best option here? Can the drives be somehow reliability attached through USB for example? Or will it be best to buy a used mobo and ram and replant the CPU? Or should I just sell the whole thing and build a server from scratch?
