Silverstone Raven: A New Concept in Case Cooling

Inside
The case design concept is indeed very different, and even if the cooling isn't any better there are almost certainly people that would still approve of this case design. However, we think that the cooling design is effective, since heat should exhaust easier through the top of the chassis. You can also get fresh air for some important components without having to draw air through the entire chassis; for example, a power supply with a 120mm fan on the bottom gets direct access to fresh air. Higher end GPUs should also get access to a lot of fresh air from the side panel vents. A 120mm fan serves as the primary exhaust at the top of the case, and Silverstone again uses positive air pressure with more intake fans than exhaust fans in order to optimize cooling.
Towards the front of the case are six hard drive cages that can be removed by opening the appropriate lever and sliding them out. This allows you to easily install hard drives, and small rubber grommets isolate the hard drives and keep them from touching the rest of the chassis. This should reduce vibrations and thus decrease noise levels. The drive bay on the left includes a back plate that enables hot swapping of that hard drive. Optical drives use the same mounting system Silverstone has used in other cases.
One of the interesting benefits of the case design is that you shouldn't have to worry as much about graphics cards causing flex on your motherboard. They can now hang from the top of the case and shouldn't sag. In addition, you can use a support bar that reaches across the motherboard to help secure the graphics cards. The bottom of the case has a ton of space, so you can easily install even the longest of power supplies. The air filters at the bottom are easily removed for cleaning, although you will need to remove the side panel for some of the filters. Finally, there's a bit of extra room behind the motherboard where you can route some smaller cables if you desire, but it's not a particularly large area so you won't be able to route all of the cable harnesses that way.

All other reviews I've read gave it low ratings due to poor (cheap) plastic quality, tight space around video cards, awkward cable management and poor cooling (!). Many people complain the case arrives with broken/jammed doors. I'd stay away from this one. CM Cosmos S or Antec Twelvehundred would be my choice.Z.

I liked this orientation, which is better for these longer GPU cards that run into the HDD cage. My Antec P180 cannot properly fit hard drives in the same horizontal plane as the GPU. Though it can fit a few drives beneath the MB chamber in the PSU chamber, at the subtraction of the fan which is kept in this area. (My PCP&C PSU is too long hindering the combination.)I'm a bit worried about the usefulness of this case and USB Flash drives connected to the back of the motherboard. It seems to me that the case is fairly large and begs for cables with a 90 degree bend.
What I liked least was the swirling air near the CPU as shown in the YouTube video's. This does appear to be a dead spot.
My vote on the appearance, is F117 "Nighthawk". It seems they considered this too with the black bird name of "Raven".
The perfect case still doesn't exist, but I'm happy to see creative thinking!!! Good job on the review.

I think tsponholz is right, Most of these things have been done before.If I had a little more money, I would get the Cosmos series from CM, but the CM 690 is such a bargain. It can do almost everything you need to get good airflow, especially if youre willing to do some slight modifications (cutting out the hex mesh and stuff like that).
The only thing unique here is the 90° turn that the motherboard has taken, I can see certain benefits from that. I'm imagining all the back panel cables coming out from the top rear in one bunch, bundled together neatly. Feels rather satisfying if you're an obsessive compulsive like me. Still, I'd rather have the ability to mount more fans in the ceiling.
Having balanced intake and exhaust cfm is the way to go in my opinion. Unless you can somehow seal everything tightly, you're only going to be forcing the air out of every crack it can find and that can lead to problems like areas with very little flow.
How much positive pressure could you really achieve? Maybe if there were 3 or 4 ultrakaze 3000 fans for intake and 1 exhaust fan at the top-rear, but even then it seems to me that the pressure difference would be absolutely negligable. Just get your air flow balanced and clear up your internal cable clutter, people!

I have the CM690 in the comparison and will have the review up very soon. It provides indeed impressive cooling.RagingDragon - Saturday, February 7, 2009 - link
I'm using a CM690 for my primary PC, so I took a close look at your CM690 graphs - and I was very pleased to see how well it performs :). It's only weakness seems to be hard drive cooling, but using fewer drives and/or a stronger front fan would probably fix that. The CM690 comes with 3 120mm fans, but if you need/want more cooling it has mounting holes for: 5 * 120/140mm, 2 * 120mm and 1 * 80mm, and if that's still not enough, Thermaltake and others sell cheap 3*5.25" to 4*3.5" converters which mount a 120mm fan.glenster - Friday, February 6, 2009 - link
The Enermax Revolution PSU takes in air from the top and sends it out the back. Since this case uses positive air pressure, could you install the Enermax upside down?Christoph Katzer - Saturday, February 7, 2009 - link
Both directions possible. Would suggest (as mentioned in the article) to take the air from the bottom since it's fresh... there is a ~80x160mm wide opening in the bottom.Cardio - Friday, February 6, 2009 - link
So you can use shorter cables from your PS. Well, do they come with various lengths, no, you will just have more cable to try to stuff somewhere!Especially that inflexible 24 pin number that will be much too long. And any number of cables, USB, sound etc will probably be too short. It really didn't cool very well, anyway. Want to take the thing apart just to plug or unplug a cable. Answer to a non existent problem. I have had a number of their cases and none you could love.
Rather than a Lamborgini, it looks more like a 1950's garbage can.

Well, you can run short cables, Silverstone makes them for their power supplies, and I am sure they would like to sell you both an expensive case and an expensive PSU with optional cables.elfy6x - Friday, February 6, 2009 - link
I enjoyed the article. The multi-bar graphs are really interesting in showing all the different temps. Could you shade them with slight variances? It would help A LOT in reading the temp data you have. Just a suggestion.
