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.
Yes it is a lottery, but chances are horrible. If you think you can hit chances like that, than you are better off playing a real lottery and if you win, you will win much more than hitting a block or two in Bitcoin. Lol
It also depends on hashrate. I know there was a group on the forums that was renting large hash rates. They did multiple runs, and I believe in the end had a positive amount. Which is part luck of the pool they used when solo mining.
So it can be done but yes with a usb stick miner or two it is horrible odds.
