I don't recommend using an "offline computer." SeedSigner is great if you have some technical skills and want to build something from scratch but ColdCard + Sparrow (watch only wallet) is the gold standard though Im sure 100 people are going to reply to tell me why you shouldn't use it and should build a nuclear dyson sphere in your garage faraday cage basement on the moon instead, but I dont care what they have to say and neither should you.
