Will this still count as an air gapped device or do I still have to remove the hard ware networking components from the PC board?
And will it be possible for an hacker to install those drivers remotely?
This count as air gapped device but why not just invest on a hardwaware that is 100% air gapped like Keystone and Elipal instead of relying on an old PC that has the tendency of being not functional in future? You will need to import your seed phrase once your computer broke so why not invest earlier on much reliable air gapped wallet.
