I think my PC is fairly quiet but my mum insists she can hear my PC when she's sleeping in the next room even though my bedroom door is shut! I have perfect hearing and I can't hear anything when I'm in her room! The fans on my PC are virtually silent. I have 8 hard drives in my PC so I can only assume that's what she's hearing or it's the Power supply noise. I'm getting a fanless PSU so the only problem is quieting the hard drive noise.
Can anyone please suggest the quietest case possible with a link to a professional review. I do NOT want unnecessary vents where noise can escape. I need space for a 140mm fan on the back and a 230mm fan on the top or a radiator on the top with 2 fans on it. I do NOT need a fan on the front of my PC as the hard drives don't need to be cooled as they never get hotter than their tolerance.
I'm going to have up to 8 4TB hard drives + 2 SSDs so I need a large case. The SSDs will go behind the motherboard so I don't need rack space for those. I also have 2 optical drives.
Tool free hard drive installation is essential. Also when I remove the side panel of the case I like to have my hard drive SATA ports facing the side panel so I can easily connect/disconnect the cables.
