Tbh I expect him to try to invade Mexico at some point in the next few years

DAS enclosures are super easy to set up. Disk won’t be a big issue if you go that route.

If you’re planning on running containers, tbh I would not. The required virtualization layer (due to macOS being BSD-based) is going to make containers WAY less efficient. You’re better off with a system you can easily slap proxmox (or whatever distro floats your boat) on.

+1 - GL.iNet is cheap as hell and perfectly functional. It runs DD-WRT under the covers, and it’s super easy to “unlock” the full powers of the distro (literally a toggle in the basic ui, iirc). Used it on a longer trip my partner and I took a few months ago, and it was great! On-device storage is paltry, but, well, that’s not what it’s for.
