ok, so i have fitted the spu and attempted cable managment ( dont take my word for it!

), but i think it is still erm wrong lol.
And i have taken some photos too, here go:
At one instance, i used only 1 fan and as you could guess, there was vibration, when i put my hand to the case, i felt it! And that fan wasnt the side panel fan, that one was at the back of the case.
Im having 3 fans on atm so its pretty noisy. I dont know what next, fan controller or aftermakers fans or both!
Thanks for the advice so far, i used the (thank) button to do that as i just found out about it few mins ago! lol.
P.s. I said side panel fan was noisy but perhaps because it was closer to me than others. Imho, they are all pretty noisy to me!
@ Pob255:
You mention 4 factors: vibration, quality, speed and vents
Vibration: yes, it is there
Quality: cant decide
Speed: not too sure, i say it contributes to noise level since when i turn on pc, it's reasonbly quiet (not 100%) then gradually it gets noisier
Vents: not idea, how do i go on about checking vent noise?
