I have an older Lenovo E41 laptop that I'd like to put to practical use instead of leaving it unused. I'm especially interested in learning DevOps, self-hosting, or server administration, but I don't currently have a router. What projects would be realistic to run on it, and how could I connect to or manage the machine without a traditional home network?

Home Assistant would be a practical project, especially since the laptop already has its own screen and keyboard for troubleshooting. You can also learn backups, scheduled jobs, permissions, logs, and service management. Without a router, connect the laptop directly to your main computer with Ethernet, or use a phone hotspot or another device’s hotspot for a temporary network. It will mainly be accessible locally unless you later add proper networking.
For learning DevOps, I’d install Linux and build a small lab: run a web server in a container, deploy an application from a Git repository, automate setup with Ansible, and add basic monitoring. You could use the laptop’s Wi-Fi hotspot or a direct cable for access while experimenting. Avoid exposing services directly to the internet until you understand firewalls, updates, authentication, and the risks of port forwarding.
A low-power home lab is a great use for it. Install a lightweight Linux distribution, then practice with Docker or Podman, SSH, Nginx, Git, and basic monitoring. You could host a private Git service, a small web app, a wiki, or file storage. If the laptop has limited RAM, start with one or two services rather than a large virtual-machine setup.
That’s exactly the kind of hands-on practice I’m looking for. I’ll probably start with Linux, Docker, and a local web app before trying anything public.
