Judging by the number of problems reported by Raspberri Pi users in bitcoin node groups on Telegram, I would recommend using an old laptop or mini PC.

Much more stable, cheaper (nowadays RPis are difficult to find and expensive) and just as easy to set up (if not easier!).

I built my first node in an old Lenovo Thinkpad laptop with external 2TB SSD. Ubuntu + Bitcoin Core + Electrs

A few months ago I watched K3tan's/Ministry of Nodes Ubuntu NodeBox 2022 Series and I bought a second hand Dell Optiplex mini PC in which I installed: Ubuntu Server + Bitcoin Core + Fulcrum + LND + Ride the Lightning.

I absolutely recommend checking his playlist for anyone looking to build or upgrade their node: https://www.youtube.com/playlist?list=PLCRbH-IWlcW2A_kpx2XwAMgT0rcZEZ2Cg
