Totally still possible! If it’s a node for personal use, making payment, zaps, etc. no issues. It’s more when people try running a routing node with lots of channels they run into problems pretty quick!

My first node was almost identical, same RasPi and case- only difference I had the expansion board to use NVME drive which I thought was much better since there was no need for the external usb drive- that’s a bottleneck and potential point of failure imo.

But again for personal use / experimenting it’s more than fine as-is!
