What do you guys thing is a good Full size tower and a good cooling for my AMD FX-8320?
Cooler master - HAF X : As i own this case myself i can say it is a sturdy and well built case, it is 70% metal and the plastic parts are strong and wouldn't break anyway as they are mostly cosmetic and have no weak points. The case was also designed to have great cooling even in poor cooling systems, the airflow through the case is great as long as the bottom is lifted a little off the floor "on its built in stands". I have mine on a carpet and i run great temperatures with a 680/i7 . 4.9Ghz/16GB Ram when running battlefield 4 and all arma games ( i rarely get above 40-60 degrees celcius ) i mostly stick around 30-40. (i do have water cooling listed below and 4 fans)
Thermal take water 3.0 - Now as you are buying a full tower case i assume money wont be your no-one worry, Though this is a fairly expensive cooling system it is well worth it. It will do a great job at keeping that CPU temperature down no matter what sort of case, cooling system you have. It you can read more about this online.
GELID WING 12 PL Case fan - Any fan with a magnetic bearing will far out perform any other in terms of noise, i have all of my fans in silent mode and i cant even hear them with my headset on, and as soon as you get more than 1-2 meters away you cant hear the PC without the headset. So any fan with magnetic bearings is great.
