Silverstone Raven: A New Concept in Case Cooling

Appearance
The case is all matte black with small windows on the left side panel where users can see their motherboard and components. We are rather pleased that Silverstone didn't include a larger window, since this allows you to show off your graphics card(s) and a few other items without worrying about showing the power supply and all of the extra cables that might be present. The top of the case is rather bulky, since there needs to be room for all of the cables that would normally be at the back of your case. The left side also features additional air intakes that bulge out on the bottom of the case; in fact, the case is somewhat reminiscent of HP's Blackbird design, with some obvious changes. The front of the case sports a horizontal clear plastic part at the top that glows blue when the system is powered up. If you use the appropriate motherboard connector, you also see a small red flashing light in the middle of the blue illuminated bar for hard drive accesses.
The front door is quite cool: it slides down into a recess when you push it. It will stay there until you tap it again, at which time it will slowly slide up to its starting position. Above the door in the horizontal glowing bar you find the power and reset buttons. Behind these buttons is a door that you might not at first notice, which provides access to some standard I/O ports -- USB, audio, and FireWire.
Moving to the rear of the case, things take a dramatic turn from what we are used to. You are greeted by a smooth surface, since all the connectors are now at the top of the case. The one exception is the power supply, which is located at the bottom of the chassis. We think this design will appeal particularly to people who have their PCs sitting next to (or under) their desk on the floor. It's possible to hide much of the cable clutter that you would normally see if you're careful. Of course, the flipside is that you would want to have this case sitting on top of something like your desk, as then everyone would see all of the cables hanging down from the top of your chassis.
Opening the top of the case to get all of the cables and expansion ports is very easy. You turn both knobs at the back of the top and then you can lift that part out of the way. You will then have access to all of the expansion slot ports. The removable section is perforated to allow airflow through the top of the chassis, and in fact airflow would probably be better if this perforated top didn't even exist (although then we wouldn't have hidden cables). You'll also need to remove the top panel anytime you want to access the side panels, since the two lovers that open the sides are underneath the top panel. When you push the appropriate lever towards the front, the respective side panel will open.
Another noteworthy feature is that Silverstone installed filters on all of the air intakes, which should help tremendously in keeping the interior of your case free of dust bunnies. Since the case will likely be sitting on the floor, this is an even bigger concern. Just remember to clean your air filters on a regular schedule.

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.
