Using a SATA cage is a really interesting suggestion, since it can likely be used to expand the capabilities of the HM90.
The Rosewill cage will be difficult to source in Europe, but I think that putting some swappable bays into an internal drive enclosure should fit with a printed adapter into the 10" rack.
I’ll do some more digging on this direction. Thank you for the suggestion!
The technology of VPN works great for circumventing censorship. VPN can be blocked, but it’s a game of whack a mole between the state and private actors. The main vulnerability in hosted VPN is that the provider has the ability to sell you out if law enforcement comes knocking. Picking a trusted provider is key. Alternatively, there’s TOR but that isn’t perfect either, as anyone may participate in the network.
