Best setup for Windows desktop- or rPi-based knowledgebase?
I thought of this project in order to improve the learning and experience of some students I will be teaching.
I would like to set up a private knowledge base where users (for whom I create logins) can log in, create new topics, and update information on each topic. However, as the information needs to remain private/confidential, it should be served up over SSL and hosted on an encrypted disk/volume/VM. Physically, it will be hosted locally, at a friend's place. My two options for hosting this are: a desktop running Windows 7, a desktop running Windows 10, or a Raspberry Pi Model B with 512MB RAM that I have sitting around unused with a wifi dongle (I also have a spare no-name-ordered-from-China USB ethernet adapter, but am not sure if there are linux drivers).
There is a 95% chance that this will just be used for a couple weeks with <5 users who update each topic once/day, but it would be nice to have a portable solution, if possible. There should also be a way to "archive" certain topics (i.e. there is a list of "currently active" topics and then "archived" topics - IIRC, this is easily achieved) I will also need an automated encrypted backup strategy for this project. What option(s) would you recommend?
One more question: if someone is able and willing to set up something like this for me (and explaining their steps to me along the way so that I have at least a basic idea of how to fix/modify things should it be necessary), what would be a reasonable price?
