First off, it becomes obvious the Cooler Master N-200 has plenty of room with as much as 14 inches of space for not only two of your largest video cards, but also leaves you with ample room for the longer power supplies as well. Below is an example of an AIO 120mm water cooling solution with two SSDs mounted to the MB tray and one HDD mounted to the top of the HDD cage. The bottom HDD bays and top 3.5 and 5.25 bays are left open for further expansion.
In this next configuration we have the AIO 240mm water cooling system. To achieve this we had lost the top 3.5 bay above. You also have the option to remove the bottom HDD cage below, or simply slide it to the left and re-install it to pick up an additional inch. Removing the HDD cage will open up the area for two more fans for a push-pull configuration for additional cooling of the radiator.
Last be not least, we have our tried and true air cooling only. Not only is there plenty of room for the tallest air coolers, but this is where you can add the additional 120mm fan up front followed by another 120mm intake on the door. You can even add one 15mm thick in the roof to exhaust the hot air out the top of the case for awesome air cooling throughout. The best part is that you can order a windowed version of this case and show off that custom build at your next LAN party.
