Umm... What else do we need? Interwebz, raspberry pi, an admin...
3 amp adapter? (I heard 2A ain't cutting it anymore)
Firstly, I have doubts that a raspberry can handle the amount of data that is processed on a site like Bitcointalk.
Second, you need to have a dedicated circuit or dedicated IP.
Third, you needed to have a stable enough internet connection to ensure that the site is always online.
Among other things. See some photos of server locations to get some ideas of what a site like this involves.
I am not sure mate. I think this set up looks pretty capable but I ain't no expert on serverz and shiet. I only know B1 level Javascript and some A2 level node.js.
This is going to work on solar too. A 100w fold-able panel will keep this baby up for a loong time.
