If Possible U Can Afford A Micro Atx One Which Is Biggerhttps://pcpartpicker.com/product/shtWGX/corsair-case-cc9011086ww
I already have the case (I switched to this one from a Fractal Design Define R4), but I'm not happy with the noise of my current PSU (a Corsair @ 30dB) so I'm looking for a new one.
From what I've found the Be Quiet ones are, by far, the quietest active cooling PSUs (10-15dB), with the only one coming close being the Silverstones, but those are much more expensive (and still louder @ 18dB+).
I'm not too worried about temperatures though, as long as I have an actively-cooled PSU - the biggest heat producers are the HDDs (the rest is all "low power" components (GTX750Ti + i5-6500) with good (and very quiet) cooling.
