I want to build a low profile system running as a full Bitcoin node, i.e. just running Bitcoin Core 0.9+ and pretty much nothing else. What is the minimal system (in terms of power consumption) that would be suitable for this task? Just bitcoind will do, no interface or visual interaction needed.
I'd really prefer something where I don't need to build all the software manually.
A simple small netbook would do, I guess. But could I even use something like a Raspberry Pi? Or perhaps some other single board computer?
I assume it'll need at least 20-30 GB disk space (for OS + Bitcoin Core with entire blockchain). Is there a minimum amount of RAM I'd need for bitcoind?
Curious to hear what kind of system and OS you guys would recommend for this!
(P.S. to avoid confusion: I just mean running a full Bitcoin node, not mining)
