First NAS for training....?

[parabellum]

Hello, I am looking to buy a NAS as a training tool. I don't need a lot of storage, I just need experience using networks and network devices. Ideally setting up securtity and the network settings myself. I am transitioning into the IT sector and need some practical experience before I attend interviews. I am currently studying CompTia A+ and will move onto Network+ / CCNA after that.

I was thinking about something along the same lines and realized that I could use old PCs (which I seem to collect) and an open source NAS program. FreeNAS and others have been discussed in the NAS Compares videos. Especially if you are on a budget.
