DUMP YOUR RASPI NODES. Get a used mini PC or used laptop for cheap!

More powerful, only $45-75 on eBay (plus ~$65 2TB ssd, but you'd need that anyway for your Raspi node).

This HP EliteDesk 705 G4 is **overkill** for a node. 5 yrs old. Costs $75*.

Fan noise? Meh. Power draw? CPU's max draw is 35W.

Once it's done syncing, the video can't even pick up the fan running at idling speeds:

Cost to run:

15W * 24hrs / 1000W/kW * 12¢/kWh * 30 days = $1.30/mo

This cpu is 8.5x more powerful than a Raspi4.

A more pleb-friendly option is a used laptop. Has everything you need built-in (esp the BATTERY!!! Huge advantage vs Raspi). This HP ProBook 450 G3 is running an 8yr old i5-6200U (3.5x more powerful than a Raspi4). Also super-quiet and low power (15W max cpu draw).

As I go down this rabbit hole, I have more questions. Which Ubuntu software do I need to install to run Umbrel? Is it the desktop or the server? Also any spec requirements I need to be aware of? Meeting with my outside computer guys soon and hoping I might score a mini computer for free. But need to know what I need to ask for. 🤙🏻

I haven't done Umbrel tests yet, but my guess is the non-desktop Ubuntu is fine because Umbrel's UI is all web based anyway.

Once you have the hardware, it's easy to experiment with different ubuntu installers on a USB stick.

best thing to use on a usb stick is ventoy.net. then you can just have many images on a single usb. a distro hopper's dream

Yes I watched a video on setting up a usb to boot from and install. I was thinking the same thing that it would be the server version of the Ubuntu and then install Umbrel. Will consult Umbrel Group before I finish. This is a winter project but gathering stuff.
