I suggest you start with a small amount and test different services to build a lightning node to gain deeper understanding of concepts before building your long term node.

For example, on Voltage Cloud you can buy a bitcoin testnet node which allows you to experiment without risking real bitcoin and you only have to pay for it by the hour. You can learn how to use Thunderhub and LNbits, etc. Let me know if you need testnet coins.

Then, you can graduate to start an Umbrel node that you run on an old Linux laptop. Later you can build a raspi and run Umbrel on it.

After all this, you will have the understanding and you will be able to decide what sort of node you want to build.
