The audience of my channel is different. I like Start9 hardware a lot, but if you can (and I know it's a lot to ask) adopt a paranoid stance by using extremely well reviewed stripped down distros, avoid GUIs, install what you need only, learn how to harden/setup a server and manage users/processes, verify manually, keep bitcoin software segragated from other stuff, and keep yourself well informed about technical/political issues that might require individual decissions on your part as a peer in the bitcoin network.
