Does the layout of the case allow good access to items such as RAM and the power connections This is a hard thing to judge if you don t have the motherboard installed but try to visualize the layout.

Because more and more people have their PC in their living room but they dislike the noise from them there is a big market in sound-reducing cases for PCs. These have sound insulation built into the sides and also low-noise fans. Don t expect miracles though. Your PC will be a lot quieter after you ve changed the case for a sound-reducing case but it s not going to make it completely silent. FIX-IT-YOURSELF HOME REMEDY If you want the quietest PC possible you will need to replace a lot more than the case. Other sources of noise are the case and CPU fans as well as the PSU fan.

No matter what lengths you go to your PC is unlikely to become totally silent but it will be noticeably quieter.
