I'm using XigmaNAS with two zfs pools and only 4G RAM since like 8 years, also on a seemingly underpowered machine (Atom D410). Granted that it doesn't fly, but for home use is more than enough say for serving on the home LAN multiple HD movies at the same time, provided one doesn't load it with other more heavy services. Mine is currently only serving files through NFS and SMB and bittorrent; all else is turned off.
BTW, currently working around a bigger one that will run on a faster mini PC and a 8 bay USB3.1 enclosure. I'm a little wary about USB connectors in this context, and I'll likely have to secure cables firmly to avoid wearing and accidental pulls, but so far results on the bench are promising.
