Other idea since you already crossed out cpu/gpu, would be to put your ear next to the harddrive, although i never remember a faulty harddrive that was humming. Worth a shot though.

Its not the PSU fan, as it only comes on due to heavy load & a quick dust blast at start up. And the blast only lasts 5 seconds if that. But I'll give the girl a clean out today and see if I hear it any time soon.

Also I'm not to sure if its my top fan (220mm) on my case. Next time it happens ill also try pull the case fans out and see if it continues. It sounds to me if its vibrations from something as before that test video i had put my hand on my case and it had made it quiet. So I'll go around tighten everything today as I give her a clean.
