When I first got into this, I was exactly where you are — no clue about models, specs, or setup. What helped me was focusing on basic bitcoin mining machines that had good community feedback and didn’t require custom firmware or advanced cooling. I started with an air-cooled model around 130 TH/s, low noise, and easy plug-and-play installation. I avoided hydro-cooled ones because they’re more powerful but also much more complex and require a lot of prep. The key is knowing your power limits — check your outlet capacity, breaker load, and ventilation before buying anything. Also, don’t forget about noise; my first unit was louder than I expected and I had to move it to the basement. If you're serious, go for something that doesn’t need daily babysitting and has stable firmware. It’s also worth joining a few mining groups — people there are super helpful when you’re figuring out the little things like power connectors, pool setups, and firmware updates.
