I'm selling my PC and the person I'm selling it to lives a good 30 minute drive away. I hear laying it down flat is good enough and the heatsink and graphics card aren't really heavy either. Would I also need to worry about shocking my case while moving it? I don't have the original box it came with though, I do still have the bag it came with though, the one that sort of feels like foam (which I honestly don't know what it's called). Can I just use that or is that all just unnecessary?
