Storage is kind of important. As in, you don't want unreliable crap even at home, just because you have some preference for small and silent. I hope things work out, but you really should have invested a few minutes and assembled something yourself. File-system-wise, using anything except ZFS for storage is kind of silly in this day and age.
The reason for that is something I myself experienced - I put together a system for home some years back built on OpenSolaris (which is now OpenIndiana / Illumos) and due to pure laziness lost the entire boot mirror after I was too slow to replace the first drive that failed. For some reason, I had a drive in the RaidZ array (the equivalent of Raid5, basically) that had just gone bad too. So out of five drives total in the machine, three died.
I lost no actual stored data. I reinstalled the OS onto a new single hard drive and spent literally a few minutes setting up one user account with the same UID I had used before, then did a "zpool import -f storage" and had my storage pool back and mounted in exactly the same places it had been mounted on the previous install. The only thing remaining to do was to replace the faulted drive in the storage pool array and let it resilver. And all the data on ZFS is checksummed so I know for a fact that every bit of it is intact.
Sure, if I had lost two drives in the RaidZ array I would have been toast, but the sheer ease of recovery even after losing the entire system drive is staggering compared to other file systems.
I'm as fond of Linux as the next guy, but nothing in the world beats a storage system based on OpenIndiana (or for that matter, Solaris, if you're willing to pay) and ZFS for reliability and feature set. You can use that to assemble anything from a near-silent home system built around a Fractal Design Node 304 case and a 6-sata-port SuperMicro Mini-ITX motherboard with IPMI for a few hundred bucks total to something like the multi-petabyte system that Korea Telecom runs on Nexentastor.
