I'm very new to RPI and I found this link here to create my own Cloud Server, which is what I would love to do - it would be really useful for me. Given the steps and requirements on the page, what RPI setup would you suggest? I would also like a touch screen on the PI if that's possible?
Make sure you have a good power supply (i.e one with a 2.1A port), you would want a small battery backup potentially or a small standard UPS. The Raspberry Pi foundation has released a touchscreen for the Pi, it goes into the "other" camera port.
For network connectivity, I'd go with a direct ethernet connection, if it will be WiFi, make sure you have a good WiFi dongle. You will also need to put together some sort of port-forwarding (router) configuration to get access to your pi from the web.
You will also be needing an external hard drive (I would assume).
Make a list of your requirements and make sure you do your research. Plan for the project to take 10X longer to put together than you anticipate (especially since you are "very new").
