I wanted complete silence too, but realized it's way easier to just move the PC elsewhere. I moved it into an adjacent room, made a small hole in the wall for cables (10M hdmi+usb+audio) and that was it, it worked perfectly. The price was trivial - about $40 total for cables. I already had a usb extension hub. Sadly, that's only useful for 60Hz, as high refresh rates require a short displayport cable to work. For this reason I no longer use this solution. If you're ok with 60Hz and have compatible room layout I recommend this. The biggest advantage is that it's completely PC agnostic, which makes upgrades way easier, as standard cooling solutions are fine.
