how much does it cost in term of electricity per month?

If you run all the drives 24/7 I would guess you are looking at somewhere around 400W assuming a power sipping minipc as the host. This can be extremely optimized if you intelligently spin down disks when idle, probably down to >50W average.

Cost will depend on your electricity contract, but will propbably not be a thing that would stop you if you want to do this.

From "negligible" to "I have another house inside my house" levels, depending on your hardware.

A close friend of mine runs a single beefy server at home, which is currently ~35% of his monthly bill if I'm not making mental-math mistakes.

As far as serious hobbies go, 35% of monthly electric bill is not breaking the bank. How much do people with other hobbies spend monthly on parts for their project cars, race entry fees, gym fees, "high performance" gear, Track fees, etc?

I didn't imply that it's a high amount. It's just an example I can refer reliably.

I'm not a stranger to expensive hobbies. I have at least a couple of them. Photography and high end stationery being two of them.
