Hopefully someone can answer this question.

I have a spare raspberry Pi 1 (b+).

Would it be possible to use this to host a sia node on siaberry,  and use this node with a storage contract as NAS?  Not for steaming, but just to store large files i don't use so often.  I mean provided the SD card is big enough for the OS and blockchain.  Then buy 1 or 2 TB with a contract?

If it is possible, does anyone know of any guides how to set this up.
