I've wanted to try hacking a Pogoplug ~($12 on eBay with free shipping right now, as I just saw on Dealigg this week) to become an OSD (inserting one 3TB disk). I believe all of these have a SATA port, though the amount of RAM varies. These lesser ARM processors are pretty slow for this kind of work too. After much thought, I decided it would probably be better to make the Pogoplug an iSCSI target.
I guess the topology would be to run ~10 such Pogoplugs on a layer-2 gigabit switch with a 10GbE uplink. Then, a copper crossover cable would be used to connect to a 10GbE port on a desktop. The desktop would use iSCSI to mount the Pogoplugs. These block devices would back 10 OSDs with a some quantity of trim'able USB3.0 thumbdrives for OS and journals. Multiple a few times... profit? Anyway.. Back to work. :-)

It's a pity Pi doesn't do SATA. Otherwise all you'd need's a working arm
port and some scripting...
