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.
this was a good strategy with various altcoin, many were renting an enormous amount of hash back than from betahash miningrig ecc... and pointing everything at every new altcoin, then dump fast, it's go without saying that a thing like this did not last so long...
but it was very profitable risk were minimal, occasionally dev screw the launch and you lose quite a good amount, from 0.1 to 1 btc
