In my opinion the Corsair air 240 is the best. It comes in white and black and it has a second chamber for cable management which is a hassle with small cases and it allows for many cooling options.
For psu you can get a 550w evga power supply because you are going to buy a graphics card or you can get away with a corsair CX 430 for a PC without gpu. The mobo and the CPU are compatible.
