I would also suggest a Trezor wallet because every time you access it your
login pin 'pattern' is randomised.
I will do the same, and I tend to agree with this.
Instead of searching for a refurbished or brand-new laptop for the DIY hardware wallet,
why not to choose for a ready-to-use hardware wallet like Trezor?
IMO, DIY setups require technical expertise to configure securely before use.
Unlike Trezor, it is purpose-built with an intuitive interface and seamless integration for managing crypto assets, while also keeping your private keys isolated within the device, never exposing them to your internet-connected computer, which can help avoid malware, hacking, or keyloggers.
Plus, it was designed to resist both physical and software tampering.
