You could run a Solana validator. Here's a calculator if you want to get a sense of the potential revenue: https://www.aeropool.io/validatorprofitcalculator

Bare in mind:

- bandwidth will be high, say 20-25 TB/mo outgoing

- ram you might be tight, if you have the chance to grow to 384-512 it'd prob be better

- you'll need at least 2 boxes, one for mainnet and one for testnet. Testnet will be "less important" so you can still run a lot of other things on that machine

If I were you, assuming you find this interesting, I'd start a testnet node on your current machine, get practice with it, as I was mentioning keep running your other services. And then if you're convinced you just rent a 2nd machine on any of existing providers/your favorite location to run mainnet.
