Came across this pretty awesome piece of hardware - a well-built open source Network Accessible Storage (NAS) - called Evercube.
The design is open hardware, available under a Creative Commons Attribution license. And it looks good as well - a stainless steel 6-inch cube, housing five 2.5" hard drives - not the big drives but those smaller laptop ones.
Which makes it quiet enough to run in the living room.
But then it is expensive. So - maybe not the best use of the monies, but never hurts to know that there are open source options that look good.
