Customer Reviews

Cooler Master CM690
I just built my new computer in this case and found: the cooling is awsome. With 7 possible case fans you can use the slowest (and quietest fans) that are available. The side fans will make a whine because they are against the inlet grille, so move them away with spacers. I used two old 12cm fans, cut the guts out and used the outer rings for spacers. Lots of room even if you buy one of the Orb series cpu coolers. The ON and hard drive LED's are on the right side prompting you to place the case on your left if you want to see them. Mine had a weak red hard drive LED, so I replaced it with a super-bright red LED and all is well. The case is very sturdy and all components mounted easily. I recomend buying the add-on 12cm fan filters for the side fans to keep dust collection on inside parts to a minimum. The wire management clips do a great job keeping things neat inside for max airflow. All done, my computer is the quietest rig I've built and it looks great! I would buy this case again and recomend it to my friends. Oh ya, the plastic retaining clips for the cards are marginal, but they do have the holes drilled and tapped so you can use screws for a stronger mount. Good job, Cooler Master!

Not just a nice looking case....
This is a great case, I had considered the Antec 900 before ultimately buying this one (not just because it is cheaper)

Pros:
-Budget friendly
-Great Looking
-3 120mm fans included
-Tons of airflow
-Very easy to wire to keep airflow restrictions down
-Bottom mounted power supply
-Tool-less (except motherboard mounts & PSU)
-Extra drive/mounting screws along 5.25 drive bay cage
-2 USB, 1 2394, & 1 eSATA external ports on top of case (slightly inconvenient, but very handy)

Cons:
-NOT IDE Hard Drive Friendly, I had to bend the bracket out where the plugs meet to fit it in there, but it doesnt impede the funtinality or look of the case.
-Clear window panel available according to Cooler Master's website, but nowhere online to purchase.

Awesome!
Boy I was I happy when I first opened this case.

Everything smelled so fresh and new when I opened it, and when I took it out of the box, I was already please. The design is simple but very sleek and pleasing to the eye.

Having the 2 USB, Firewire, eSATA, and audio ports on the top is very convenient. No bending down to reach anything, and they don't poke out above the surface of the top, so there are no worries if one needs to put anything on top of it.

Also, even though the power/reset buttons are on the far right, they're very nice. No ridiculous design. Just simple. Plus, they're firm, so there is no risk of accidentally hitting the button and shutting off the system.

As for the ventilation, I am very satisfied. It comes with two huge fans already installed with room to install more. Not to mention that there are pockets for air all over the place (top, front, back, even underneath).

The movable hard drive bays are a big plus (Although they're made with seemingly fragile plastic. The whole rest of the case is pretty much all metal.) I like having the power supply on the bottom so it's away from the hot motherboard and CPU up above.

Another good thing: The case has little, rubbery legs on the bottom so the metal doesn't scratch on hard surfaces.

Everything is VERY organized. Cords aren't nearly as entangled as they were in my old system.

Only cons:
1.) As previously mentioned, the hard drive bays are plastic, which may break.
2.) It only comes with one front slot replacement for 5.25" drives (Not really a big deal.)
3.) If one has short power supply cables, it may be a hassle with the power supply on the bottom. But, my GameXStream 700w supply has very long ones. :)
4.) The side door takes a good pull to take off. This may be a good thing if one has children. But, it also takes some practice to put back on.

Overall, excellent job, Cooler Master!
