My colleague has a R-PI running as a NAS and he is actually really positive of it.
But he is using a wired network, so I probably going to buy/find a cheap wireless router that I will configure as a AP and pull a small cable to the R-PI.
The R-PI doesn't need to be fast, it needs to be reliable
So now I need to find out how to build a firewall.. hmm
Can't I use the AP for that?
