Looking to build my next system to be as quiet as possible and wondering if this looks like a quiet system? I am not sure about the Corsair Obsidian 800D due to restricted airflow as there is only 1 intake at the bottom . I would be reversing the Corsair H50 on the back but still not sure about airflow in this case, especially when trying to make it quiet. Specs: Intel Core i7 920 D0 Stepping - Processor Asus P6T Deluxe/OC Palm Edition - Motherboard Patriot Viper 6GB (3x2GB) DDR3 PC3-12800 x2 - Memory Corsair HX 750W - PSU Corsair Obsidian 800D - Case Corsair H50 - Processor Cooling Scythe Kaze Maru 140mm 1200RPM x2 - Extra Cooling LG GH22NS40 22x DVD±RW - Optical Drive Already got hard drives & GFX sorted/waiting to see what happens with ATI/Nvidia war, anything else I'm forgetting or overlooked? Any suggestions on quite cases/cooling would be appreciated, ideally I want an all black case with black insides but suggestions welcome. I have an old 10mm Asetek water cooling kit not sure if I should bring this in to the equation, anyone know if I can convert this to 1/2 tubing easily? Any suggestions on water cooling would be appreciated .
