I work in a computer shop and have access to cheap old computer parts. Core 2 duo, etc. Stuff that won't run Games and video editing software, but can run tails just fine. The idea would be to set up a cheap laptop or desktop that you would not have a lot invested in that could be disposed of quickly if need be. Around 1 BTC for a laptop, or .75 BTC for a desktop.
You can buy cheap, throw-away laptops right now for less than 1BTC lol.
