This is one of the hilarious questions I come across asking about storing crypto. You can store them in any laptop or use exchanges as these things do not require any specific processors and do not take much hard disk space or ram usage.

The important thing is that in which ever laptop you install the wallets, make your the latest version of Ati virus is install in that laptop and also try not to surf Internet from that laptop and even if you do, try not to click on links which you do not know.
