Cooler Master CM 690 II Advanced PC Tower Case

I've been a proud owner of this case for about 5 months or maybe even more and I have explored every bit of this case.
Let's begin with the looks. This case looks great from any angle you look at it, but personally I really love the front side at night with the led fan turned on. I can't really say that this case has something that looks ugly or out of place, personally I could say that Cooler Master did a great job of not putting useless stuff on the case.
Now let's see what we have on the exterior part of this case. Front doesn't have much to offer at first glance but wait you are looking a completely removable front side that is covered in dust filter from top to bottom. The front side can be easily removed by pulling it from the bottom and it reveals a 140 mm led fan. On the top you will find the Power button, two activity leds, two usb slot's, microphone and headphone connections, e-sata port and front fan led on/off switch. Also if you remove the slide on the top you will reveal a hot swap drive bay (quite useful i might add) also you can see a top 140 mm fan behind the mesh inside of the case. Turning the case upside down will reveal it's massive rubber feet and by saying massive i mean it, these feet are about 1 cm in height and provide an exceptional job of canceling case vibrations (the rubber is quite rigid so don't worry about it falling apart). The last but not least is more dust filters on the bottom, although there's no filter in the psu area as it needs to be installed separately (the filter comes in the little cardboard box inside of the case).
Now comes the fun part. The interior of the case is all black as the exterior, and the insides allow you to play with cable management as you please. By the way the hard drive bay array can be partly removed only leaving 2 places for hard drives. If you have only one or two hdd's i would highly recommend removing the unnecessary drive bays since it greatly improves airflow. There's also a rear 120 mm fan and if you look up you will see the earlier mentioned 140 mm fan and that's right the top also has dust filters.
And as a closing comment if would like to add that personally I do not quite understand the reasoning of placing two additional fan places on the left side of the case. Why? Well why would you need to disrupt the airflow when the air is already going out from the top and rear. If you please just add another fan to the top and your PC won't overheat whatever the conditions are.
