Cooler Master HAF 912+ or HAF 912 Advanced ( has USB 3 ports on the case instead of USB 2). Using them for years. The one sitting next to me is almost 4 years old. Stock front and rear exhaust fans still working and they have not become noisy. Options for top exhaust and side intake. Slots for 4 optical drives/fan control or whatever you wish, or 3 of them + smaller card reader. Removable HDD cage with 4 drives, 2 more drives in the non-removable below. Solid build, easy assembly, lots of space for cable management. The HAF 912 is still the one of the best price/performance cases out there. If you like the looks, then cooling won't be a problem.
If you don't like the HAF then I can suggest Enermax Ostrog GT. Cooling is simmilar to the HAF. I really like the aesthetics of the Ostrog but the side window made me go away. I don't like side windows but that is a personal preference. I haven't build a system with the Ostrog GT but a friend is quite happy with it. Good luck.
