I have had this case for about 6 months now. I have had absolutely no problems with this case. When I originally installed my dvd drive it wouldn't stay in place. Very disappointed! I took my time and checked it out. The only problem with not holding a drive in place is a matter of very slight adjustments to the side rails. The drive needs to fit snug and square. If it doesn't a very slight adjustment to rails and you get a good secure fit. Took about 30 seconds to adjust and secure. Second one I knew what to do and it took about 15 seconds to install. Both units have been in and out a couple of times and they always lock right back into place. Absolutely a great system when properly adjusted. My side covers work perfectly. When I have had a issue with one being contrary to close it has always been a wire that has gotten in the way. The fans are supposed to blow air THROUGH the case... not just into it! Leave them mounted the way they come! Expensive case but very good value!

very good case,excellent cooling,touch sensitive power, this gets a rating of 4 stars because it's not truly tooless. I had to screw in my dvd drives b/cause case dosent do a good job of holding them. u have to screw in the HDD's in the HDD cage. Despite what some ppl ma say THERE IS NO NEED TO SLAM ANYTHING on this case. If u have to slam the side pannels ur doing something WRONG. Accssing my components is a charm; cept for the HDD's.

--note: THIS CASE IS SO HUGE YOU CAN FIT A CONTORTIONIST IN IT. Still had chalk marks from machining. Lots of room and very simple to put together. Has fans galore.. but some of them were facing out so had to turn them in screwing cooler master fans in was hard pretty sure I stripped a few screws. Two problems though the latches that hold DVD player / fan controller don't really hold I can push the hardware inside but not overly problematic. And the side door with the fan is a bugger in the sense that its hard to close. Tricky at first, place both hands at the top griping the bar with both thumbs facing down on panel. Then forcefully SLAM AS HARD AS YOU CAN.

Great case, lots of room inside, incredibly large 200mm side fan, and looks great. This case is made by coolermaster and so just to start off with i also bought the coolermaster V8 cpu cooler until im able to afford a watercooling system. As you can see both products are made by coolermaster, but when your V8 cpu cooler is mounted on your cpu, your unable to close the side door which has your 200mm side fan? WOW! What a surprize, door wont close if you remove the 200mm side fan!!!! It was a big dissapointment knowing that both products are by coolermaster and is unable to be put together!!!!
