Frens, I need some hardware suggestions for a full node + lightning node...

We'll soon be flying home for two to three weeks and I intend of using the time to set up a full node when I have 4 stationary walls.. ^^

RaspPis are crazy expensive rn so that doesn't really make sense I believe. I do have an old Pi3 lying around but I think it's only the 1gig RAM model which will be insufficient from my understanding.

I intend on running Umbrel on it, rudimentary Linux skills already aquired but eager to learn more about it and intend on doing so until we're back home (installing ubuntu via VM on Mac rn and got myself some more literature -> suggestions welcome btw).

Will set it up behind an OPNsense FW (hardware recommendations welcome again, was thinking about a Protectli box?) which will be set up in the process as well.

I'm not a coder/developer but a doctor (albeit a pretty geeky one...). So no "self-built server in a 19" rack"-suggestions please... in the future, yes... for now, no. ;)

+1 for Protectli. I ran both OPNSense and a node on it for some time as virtual machines but admittedly it was on the slow side.

Now I have an old Lenovo Thinkpad i7 for my node and other self-hosted stuff. Cost about $300 and it’s a beast. The battery is like a a built-in UPS 😉

⚡️thanks.

Yeah I somehow don't like the idea of running both things on one machine.. one because I don't have a proper understanding of the whole compartmentalisation (is that even the proper word?) and two because I don't trust the security model if I'm not fully understanding what I'm doing and rather distribute it to a specific machine other than the FW itself.

Didn't even think about a laptop yet but the battery as UPS makes complete sense to me. 🤙

Yeah there’s different ways of doing it but I agree that if you’re new to this, keeping them separate is going to be the way to go.

I have a sysadmin / DevOps background so I’m more at home with VMs/container. My setup is probablt way over-engineered for what I’m using it for 😁.

For the laptop I got this model and replaced the SSD with a 2TB one: https://www.amazon.com/Lenovo-Thinkpad-Display-i7-6600U-802-11AC/dp/B08WT481PQ

Yeah you do have a slight advantage there. 😂

Thanks a lot buddy, I'll have a look. Did you swap the SSD internally? Was that hard? Or just plug in an external one?

Internally, not hard at all. A small scredriver is usually all you need. Youtube will probably have a how-to video for whatever model you end up getting.

If you decide to go that route and run into any issues/questions, feel free to hit me up!

Thanks mate. 🙏

I’ll dive a little more into hardware as well… seems like the protectlis have also appreciated in price a little…
