Having run a similar setup (self-configured) on a Raspberry Pi I see one major issue - the Pi has an ability to damage your file system after prolonged use. I've had this consistently happen every 60-90 days of use. There are hundreds of reports of it in the forums. (Search for Raspberry Pi corrupt filesystem on Google)
My question is - how do you plan to account for this?
