Silverstone Raven: A New Concept in Case Cooling

Conclusion
The Silverstone Raven comes with many great features. Changing the orientation of the motherboard isn't entirely unheard of, but the case design as a whole is very innovative. For example, you can use shorter cable harnesses from your power supply, and you can easily guide cables through the case and avoid blocking airflow. Installing components is also extremely easy because of the large interior space.
Overall build quality is exceptional, which is what we have come to expect from Silverstone. Even though this is a steel chassis with lots of plastic, you still feel like you got a very high-end product. Cooling performance is also good in most areas, particularly CPU and hard drive cooling. Ambient case temperatures were higher than usual, but we are inclined to believe that has more to do with the location of our sensor rather than being a clear problem. GPU temperatures are also a little high, because of the panel that blocks airflow out the top.
There are two versions of the Raven chassis, one with the side panel window and one without. The model we tested to date includes the window and prices start at around $240, sans tax and shipping. Prices in Europe start at around €190 for the windowed version including tax, or you can save a few dollars/Euros by purchasing the version without a window. For those that like the angular styling of the chassis, this is a case you can fall in love with... but there will also be users that will hate the case aesthetics. Assuming you fall into the first group, we have no qualms with recommending the Silverstone Raven. The only likely roadblock is going to be pricing, but at least with you know you're getting a high quality chassis with an unusual design.

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.
