What would you do with this old PC if you had €0 to invest in it?

I have an older desktop sitting around with:

  • AMD FX-6100, 6 cores at 3.3 GHz
  • NVIDIA GeForce GT 730
  • 24 GB RAM
  • ASRock 970 Extreme R2.0 motherboard
  • One SSD and one HDD

It still works, but I currently have no money to upgrade it or turn it into an ambitious homelab project.

I am trying to decide what would be the most useful and least wasteful thing to do with it.

A few possibilities I have considered:

  • Install a lightweight Linux distribution and use it for experiments
  • Turn it into a local server, NAS, self-hosting box, or automation playground
  • Use it to learn more about local AI, although I assume the GT 730 is far too limited for most modern models
  • Keep it until I have money for a few upgrades
  • Sell it cheaply and put the money towards a newer, more energy-efficient machine

My main concern with using it as a server is electricity consumption. Keeping an older FX-based desktop running all day might cost more, both financially and environmentally, than the practical value it provides.

What would you do in my situation?

Are there any genuinely useful €0 experiments this hardware is still suitable for? Is it worth keeping, or would selling it or reusing the parts elsewhere be the more sensible choice?

A stretch goal might be 24/7 running a pi zero or openwrt router next to it so you can turn the machine on remotely.

The benefit of doing your work or learning on that machine, even if your laptop is faster, is that you can offload heavy or long running things and save your laptop battery when mobile. Want to compile something? Run some local llm job? Build a new docker image? Start it, close your laptop and go about your day. Open it later to see the thing is done and your laptop still has 99% battery. (This will require, at minimum, learning about SSH, tmux, networking, wake on lan, and probably VPNs like wireguard or tailscale, or maybe dynamic DNS - lots of fun).

You do need something running all the time to do remote WOL because those packets don't work over the Internet, but there are lots of Linux computers that use less electricity than your typical bedside alarm clock. Even an old phone might work.

Computing to support life on Earth

Computing in the age of climate crisis is often wasteful and adds nothing useful to our real life communities. Here we try to find out how to change that.
