TO all his server is a rasp pi
"Hello everyone,
I’ve set up a new Bitcoin solo mining pool:
https://solominingnode.deIn the background, it’s running on a Raspberry Pi 5 with 16GB RAM and a 2TB NVMe SSD."
Be careful about playing on a pool run on a low cost setup . It could fail and cost you a block.
The chance of a gear fail costing a block is far more likely than hitting the block.
So if you hit a 1 in 400 year event in a day and lose the block due to the rasp pi being slow you would feel pretty poorly.
There are tried and true solo pools available

have paid and are good pool guys with better equipment running the pools.
