This has been changed on the new model and you can remove the side panels without removing anything else apart from two screws. It is fairly minimalist, but does have a little bit of style. I means that if you are building your computer, you don't have to turn your whole case sideways to install the motherboard etc. You can move to a small table and install your motherboard, cards, RAM and CPU, and then just simply slide the tray back into your case. One feature is a plastic bracket near the bottom front of the case, which clips on to the motherboard tray.
Good thing is that it holds the tray steady, so dampens vibrations.
The bad thing is that the tray sometimes misses the bracket and does not pushed in fully. I have added some wheels to the bottom of the case, where the feet are. This is far cooler, and allows even easier access to the case, as you can slide it in and out. Now, with many overclockers a quality case has to have good ventilation. These two both fit, standard 80mm fans.
