Any warranty on it?
If Not open it up and take a look at the cpu fan and the PSU fan. Sounds like a fan is failing and if I were to take a guess i would say the PSU.

When you turn on the system while looking at the back of the system is the power supply fan turning or is it making the noise?
The cpu fan is the the fan that sits on top of the processor on the motherboard.
Is it turning when you turn the system on?

Not much else in mechanical parts that can make that kind of noise.
Opening the system up and turning it on is the only way to test it to try and run down the problem.
If you were to take it to a shop I can guarantee you that is all they will do.
To be safe I would suggest disconnecting the main hd so that any data will not be lost by doing this. Also if it is the main drive the sound will stop with the drive disconnected and not powered.

If so I would still say a fan is the culprit.

If on the inside then you will have to turn the system on and off a couple of times to run the sound down.

Normally this would be for checking for a short but by disconnecting power from everything but what is really needed to start the system then you can narrow down the possible culprits.
I would disconnect all drives from power and make sure there are no external drives, thumb drives, flash drives or anything like that connected to the system.
Now the only thing that can make the noise when you turn it on is the fans or the power supply. The only other part connected is the motherboard which it can't make that kind of noise because there are no moving parts on it.

The cpu fan may just be dirty but if it is also failing then it is cheaper to replace.
The cpu fan and heatsink may be one unit so it would have to be bought together. If you could get pictures of the cpu fan I could probably be a little more specific.
