TrueNAS advice from your TrueNAS video

[Enquiries]

So, I have a BeeLink AMD 5600k mini pc and 3x 4TB SSDs lying around, from another project. Can I put these together for a quick and easy and free NAS? The one downside I have upfront is that the mini pc doesn't seem to expose additional SATA ports, so I will probably be relegated to USB 3 connections for the SSDs, still worth it and would TrueNAS be a reasonable OS for this?

I was thinking that I could do a Z1 pool and get *TB useable.
