OpenWrt

Go with me here. Routers are routers, and servers are servers. Some people mix and match things, but generally, ideally, this is how it goes. And I agree.

But the router I just set up, the Google WiFi, has 4gb storage, 512mb of ram, a quad core CPU at 800mhz, is easy to flash, and only costs $10-15 on eBay all day long.

If you used it as only a little computer, no routing.. Then..

If I wanted to say... Set up a tailscale node at my family's house. Why spend $45-80, or even $130(!) on a raspberry pi with an Ethernet port, when the Google WiFi works just as well if not better for that job?

Maybe a tiny matrix server? Tiny web hosting?

Or, for a less ideal solution, but still reasonable. What if I wanted to set up a remote backup node for my main server? If my needs were small enough, the Google WiFi would be much more economical, although you'd need to add a USB hub to break out the USB ports. And there would be limitations obviously.

Or getting really crazy, you could potentially squeeze one or two bigger services onto a router, just to see if it's possible.. Minecraft server?

My question is. What is the best device for this? The Google WiFi is dirt cheap at $10-15, I'm about to pull the trigger on a second one just to play with. But I wanted to see if you guys had any other suggestions?

I tried searching the toh for similar devices, but even restricting it down every way I can think of, I've still got over a hundred devices to look at.

Basically, I think older router hardware is an overlooked, cheaper alternative, to raspberry pis, for some scenarios.
