There’s plenty DIY projects around the net with various raspberry models. You just need some knowledge, preferably access to a 3D printer, an soldering iron, some tools and other bits and bobs. It’s definetly doable, but I can understand if someone prefers to throw some money on the table and get one pre-built.
Yes, for the reasons you mention. And very, very much no. My corporate hat immediately thinks about a crapload of stuff our network drives have which is under various NDAs, restrictions to store outside EU/ETA, restrictions to store even outside our country and so on. At least our accounts have mandatory MFA and other standard safety features, but cloud storage has a different threat model than our local hardware which also makes it’s own little headaches.
I don’t play on the contract/legal field on corporate at all, but I do know that some of those NDAs have numbers big enough to bring the whole circus down and other clauses which can even throw someone in jail if things really go wrong. I just hope I’m not the scapegoat at that point.
