I have a computer which will not used, however, it is about 4-5 years old already,
is it worth to use it to mine BTC?
If yes, how much will I expect to get in 1 month

Not only it is not worth but is impossible to mine bitcoins with a computer. It is impossible to mine with a new computer. To not speak here for a old one.
It's NOT impossible. Even when we were to where it was "impossible" to GPU mine, someone hit TWO blocks with a USB miner. It's basically just the lottery. Claiming it's impossible is naive. Are you likely to? No. But if you feel lucky, go for it.
