I've used both the Corsair Obsidian Series 550D and the Fractal Design R4/R5. Both are very good cases. I think the Corsair has the edge on internal components and I'll probably be buying another one this year but they are both very nicely done. I've been using SilenX fans but going to be putting Noctua ones in the new build.

i have a Antec Solo Black/Silver Steel ATX Mid Tower Computer Case,
and a Thermaltake TR2 RX W0134RU 550W ATX12V Ver2.2 SLI Ready Modular Passive PFC PFC Power Supply,
has been working quite well for me.
 

Fractal Design make very good cases indeed. Mine's the easiest and tidiest PC case to work in I've ever come across.

I have used the Antec Solo as well, and if set up properly (as has been mentioned in this thread) it is dead quiet. 

My set-Up is Silent... Also a thing to remember is that BiG fans are very Nice because they do not have to spin as Fast to push lots of air SO, they are very quiet.  Small fans spin very fast and are usually Louder.   I have:  coolermaster HAF X 942 Case, Corsair 1200i power supply, Lamptron Fan Controler, ,1 MSI OC Edition Radeon R9 285 DirectX-12 Gaming Video Card, X79 Express chipset, Intel Core i7-3820 Sandy Bridge-E LGA 2011 130W Quad-Core Desktop Processor Overclocked to 4.6 Ghz, 32 GB (4x8GB Quad Channel) of DDR3-2400+(OC) RAM, Arctic Cooling Freezer I30 CPU Fan, 1 TB Seagate HDD,
