Got one of these for $30 from Newegg recently, and I must say, I'm so glad I picked this over the CM Mystique for $10 more. The cooling options are just...AMAZING.

The case has room for up to SEVEN 120mm fans, although that is probably overkill for most builds. I currently have it set up with 4 Yate Loon DSL-SL 12 fans (1 front intake, 1 side intake, 1 rear exhaust, 1 top rear exhaust), and the thing is so nearly silent that it only becomes audible when one's ear is about a foot away from the case. The front intake will blow air directly onto the HDD bay, and the hard drive cage has pretty decently sized openings for cool air to come through. The mesh front panel for the 3.5/5.25" bays is another great touch, since it allows a direct airflow path to the heatsink:

Another nice design feature is room for two 120mm fans at the top rear section in addition to the standard 120mm exhaust. This allows hot air from the heatsink to be quickly pulled out of the case:

The side panel has room for two 120mm fans (or 1 140mm and 1 120mm). The top opening can fit either a 120mm or 140mm and blows directly over the CPU/VRM area. The bottom intake will blow directly onto the graphics card area. I currently onlly have a 120mm installed in the lower opening and have covered up the rest of the panel with sound absorption foam:

On the right-side panel, there is an opening for a single 80x15mm fan to be mounted BEHIND the motherboard. This is useful for coolers like the TR IFX-14 or for any motherboards that have a heatsink behind the chipset area.

The inverted PSU mount is something that may or may not appeal to everyone, but I personally like it since the PSU can take air from the 120mm intake at the bottom rear of the case. The case has rubber feet that elevate it .5-.75" off the ground so the intakes have ample space to take in air. There is also room for another 120mm fan at the bottom of the case if extra intake is needed for the graphics card (since it would blow directly onto the card). Also worth noting is the fact that the PSU can be mounted upside down so that it's taking air from inside the case rather than from the bottom rear intake.

For its $30 price, this case is practically a steal. Even at the $80 asking price it's selling at now on Newegg, it's well worth it. Definitely consider this case for your next build :)

Just because the fan mounts are there doesn't mean you have to use them. I think locating the three stock fans in the front, bottom and rear would be adequate for most any system. Block off all other fan grills and vent holes as they just short-circuit the airflow.

Check my reply to another 690 thread just posted by FalcX for what might be a serious problem that I noticed with the 690.

Thanks for the pictures.

What is the exact distance that the stands provide between the floor and the bottom of the case please? Thanks!

I have blocked off all but 4 of the fan mounts with sound-absorption foam so I'm only using the front, side, and top/rear ones.

To Navid...I checked again, and the distance is 3/4 inch on a hard floor or 1/2 inch on carpet.

I bought a CM 690, going to build my rig tomorrow(i'm guessing if I have time after work) and just looking at the CM 690 and the cooling options open to me...and the case is very sleek looking as well :)

ZZF is doing it again - they change their offers quickly, so snooze - lose, the early bird, etc. etc..

Considering how much steel is in these units, it's amazing they are so cheap, $50! I have 7 - 120's in mine. The HD's run 10C cooler in this rig compared to my old standard case. The m/b is also much cooler, although the cpu/cores are still hot as I overclocek to 3.5GHz with my P5K-D/E6300 setup. I bought some Arctic Cooling low speed 120's on sale at NCIX for $3.99 (1000 rpm), and a AC tri-spd unit (also $3.99) which can spin up to 2000 rpm in the bottom to get the air stirred up at higher overclocks. Otherwise the system is very quiet, other than the wooshing air.

Where did you get the sound proofing foam, was it expensive, and can you please post some pictures of it? Thanks.

I got the foam from SVC.com. It was only $8 for more than enough to cover the bare metal spots on the case. I think I have a pic of it in one of the links. Reading from the reviews it's supposed to at least dampen some vibrations and should also block some noise from covering up unused fan openings.

Thanks. Have you noticed a difference with the foam on and without? I've been considering sound proofing my case recently and this seems like a good, cheap solution - well, good if it works haha.

Check http://www.Dansdata.com re. Akasa Paxmate which is pretty much the same as the Spire stuff - not very effective. But it certainly couldn't hurt if it blocks off a bunch of superfluous venting such as exists in the 690. And 8 or 10 bucks isn't going to break anyone...

Dan's Data is worth a visit at anytime just to get a breath of fresh, iconoclastic air...
