As the title says. I am not planning to make a living out of it, more about
- Learning
 - Contributing a small bit to the decentralisation (I read that mining pool centralisation a bigger threat to BTC than quantum attack)
 - A small positive return over the electricity cost (18 cents/kWH) will suffice
 
A few details
- Subtropical climate, so I do not need a heater
 - Minimal configuration and settings
 - My power outlet is 220 volts, 50 Hz. Single phase, type G outlet (engineering details, not sure if they matter)
 - It will run literally in my home, so not too much heating or noise
 
Are there options for beginners out there?
Also, some general metrics that I should look for when judging a miner (like when buying a laptop I can look at the RAM, HDD etc.)? Should I look for metric like TeraHash/second, or TeraHash/kwh etc.?
Apologies if the question is too broad, but you can consider it asking for general introduction someone interested attempt some mining.
