Looking for a new self custody wallet

[Lida93]

I have just built a laptop, installed a known secure linux distro and am ready to move everything I own to it.  

I want to help the network.  Especially the LN network.  Please if you have a good link provide it on how I can with my own hardware... I am not asking for step by step instructions just resources to knowledge.  .  

Out of curiosity, is this laptop built as a patent one (owned company) or it's a compilation of different components? That's by the Way, here's a link that should provide you with multi choice on resource to knowledge to about 80 different types of hardware wallets.

What about Sir if these are non-custodial wallets for altcoins, is this also possible?

Non-custodial means that there is no 3rd party holding your coins for you. But it is getting increasingly harder to find, primarily because a lack of developers to maintain them. So you will usually see closed-source wallets supporting many of these altcoins, but using a centralized exchange service to swap between them.

Which is not exactly my definition of non-custodial.
