| I actually own a CoolerMaster CM 690.
On a letter grade scale I would probably rate it a B- (80/100).
Pros
There are tons of places to put fans. The front fan LED is blue.
No door to lose or break.
Basically tool-less. Bonus: no bag of screws to lose; all are hiding on the right and left side of the case.
Lots of expansion room for 3.5 hard drives and 5.25 dvd/cd drives.
Cons
Construction can feel cheap in some places. I broke the 3.5 cover. You probably don't need a floppy (I didn't need one either, but I figured for a few bucks, why not?) so this may not apply to you.
Holes in case bring in dust, a lot of dust.
Can be noisy, pick your heatsink and fans wisely. The stock fans are okay, not quiet or noisy.
The manual is mostly junk. It doesn't explain things very well. Support from Coolermaster was mostly non-existent.
When mounting the motherboard, you can remove the plastic cable runs. This was not clear in the manual.
