Sugo Series Black Steel / Plastic MicroATX Mini Tower Computer Case

How much performance can you reasonably fit in a 23-liter enclosure? That was the question SilverStone engineers asked themselves when designing the ninth edition of SilverStone's Sugo series chassis. In a very limited space, which SilverStone defined as the limit for classifying a chassis as small form factor or SFF, the Sugo SG09 achieved performance never before seen for a computer chassis of this size. By slightly reducing storage capacity in switching to a backside-mounted motherboard, the SG09 can accommodate two 13.3-inch graphics cards with handles (longest under PCI-Express specification) with cooling provided by four fan slots. Having the power supply location moved away from above the CPU area has also increased the CPU cooler's height limit to 165mm, which is sufficient for nearly all tower CPU coolers on the market.

Designing a 23-liter chassis that can fit high-end components and cool well requires rethinking of the layout that is substantially different from traditional chassis. Even experienced computer builders are recommended to take a closer look at the included instruction manual as it contains valuable information on how to build with the SG09. Although limited in space, good cable routing is still possible by using SilverStone's PP05 short cable kit in conjunction with the mandatory cable routing design. For those looking to challenge their own PC building skills in return for a superbly packaged machine that has uncompromised performance and is portable, the Sugo SG09 is the one to get.


  • Supports graphics cards of any length
  • Supports full tower CPU coolers
  • Supports Strider Plus PSUs up to 1000W

3 out of 5 eggsBrilliant Engineering But...

Pros: -Smallest Case for matx board
-Mostly high quality parts...

Cons: - The connections from the case to the top fan broke off with just the slightest tug while the fan was unscrewed.
- The 1 piece, 3 sided cover is almost definitely going to bow a bit.

Other Thoughts: If you're looking for the smallest possible case to fit the most power in, this is it. If you want something easy to work with that you can feel confident modding often...well, this and other silverstone products are not it.

5 out of 5 eggsLinus was right

Pros: Amazing little chassis. Fits a mATX board, cpu water cooler, 2 HDD, 4 SSD, 32GB ram, 2 MSI 7970 lightning gpus and a fulll size atx psu, oh don't forget the 7 quiet fans too. A super small form factor with full tower power, maybe not the storage of a full tower but dam near the same performance.

Cons: Kind of a finger print magnet, but easily removed with a clothe.

5 out of 5 eggsMy second One

Pros: Fits my new FM2) Build Excellent. Put a corsair 600 wat modular Power Supply In No Problem. Modular Makes life easy. I started with a FM2 athlon until my 7000K Kaveri arrived/was released. The thing runs very cool. I have a SSD & a 500GB data drive installed. I put 2 92mm silentX fans in the side for extra cool...

Cons: None For Me

Other Thoughts: I have My kaveri With A Gigabyte GA-F2A88XM-D3H. The fan controls on this board allow me to run Silent. It's A Great case for HTPC/Light Gaming.

5 out of 5 eggsWell designed case

Pros: Smaller than some ITX cases, Well designed, great cooling for SFF. ample space. Allows SLI

Cons: Sometimes hard to get covers to seat right. Could use Tie-down locations for cables, but not a big deal. No window to see how beautiful and clean everything inside looks.

Other Thoughts: This case is about as small as your are going to get and still be able to run SLI setup. The Silverstone team put a lot of thought into the design and give you multiple configuration options as well as cooling options depending on your hardware. I would have preferred more options for the DVD drive, because slot loads are rare and expensive but for now I am just going without since I have access to an external.

I have no complaints about the PSU cable or size allowed. I have a Rosewill 750 HIVE PSU and it fits with plenty of spare room. I ran thepower cable up and around the edge of the top fan and its out of sight and just the right length to make the journey. There are literally NO cables running across my case. There are ports everywhere for running cables. Its just one big open box for great airflow. All the cables can be tied up on the back side with the hard drives.

I recommend if you are using a small cooler or some air coolers and have a non-reference GPU to use the default top fan layout as intake. It will bring cool air into the case for your CPU. Otherwise your cpu will run very hot with the heat generated from your card. If you utilize water cooling, I suggest turning the top fan around and use it to evacuate heat from the case. Your GPU will thank you, especially if you SLI.

3 out of 5 eggs Good, but one problem...

Pros: I ordered this case because it was compact but could fit a full size graphics card. Not only could it fit the graphics card, but also a coolmaster 212 cooler. The case is well laid out, and I was able to fit nearly all of my components easily. And USB 3.0.

Cons: The psu I chose (corsair platinum series) has the power cord connector on the right side, which would be fine for a regular case. However, since the psu is plugged in inside of the case, the cord supplied by silverstone hangs off the power supply, and obstructs the intake fan. This forced me to remove the fan, just to close the case.

Other Thoughts: If you want to buy this case, make sure our power supply connects in the center.

5 out of 5 eggs

Pros: Small, cools well, holds all you'd need. Solid.

Cons: Sort of a pain to build, but really it didn't take any longer than it usually takes to build a computer. Just different. If you read the directions you should have no problems.

5 out of 5 eggsGreat Case!

Pros: I used to buy Cooler Master cases exclusively until I was on the market for a compact and transportable MicroATX case. The quality and construction of this case is incredibly solid. For what may seem like a very confined space, it offers room for virtually any size component you have. Air flows surprisingly well through this case. Fan filters are also an awesome addition, very easy to remove and clean.

Silverstone, you have earned a new loyal customer!

Cons: For its size, it's rather heavy, but this won't matter to you if you're not constantly transporting it.

Other Thoughts: This case is not for noobie builders. Be prepared to get creative with cable management, as you should already be doing anyway!

5 out of 5 eggsGreat Case

Pros: Compact design, unique layout, quality throughout.

Cons: None.

Other Thoughts: I own two of these now. By far the best case I've ever had. It's absolutely amazing how much space there is on the inside. Fans are silent. It's solid, not cheap and flimsy. It's a great case.

1 out of 5 eggsWhats to like?

Pros: Looks nice

Cons: Where to start?

1. Better buy a Silverstone Strider PSU.

2. Better buy the short cable set ($25)

3. Better buy the special optical drive cable ($10)

4. If you are going to need an optical drive it must be a slot load. And make it a 12.7 mm drive.

So far, we've added another $100 or so to be able to use the case (cables and slot drive).

Now, lets start building.

Whoops, the special cable to run from the PSU to the back of the case is a good 9-10 inches too long. And, it's a custom cable. NO excuse for this.

Whoops again. IO shield refuses to mount securely in the case. Trying to get it to seat requires removal of a fan. Oh well, I guess the MB will hold it in place. :)

And the fun has just begun.

Other Thoughts: I really won't be buying any more of this model.

5 out of 5 eggsGreat case

Pros: Small, designed with lots of room for putting components in. Runs very quiet and cool. Did I say it was small?

Cons: Only con is putting the stuff in. Hey, what do you expect with a small case with all that hardware!

Other Thoughts: I put 2 gtx 260s in there, a 212 cpu cooler, 1000 watt power supply (not a shallow one), 2 regular hard drives and two SSD drives. I didnt add any extra fans or anything. It hasnt gone above 30 degrees C at all, run more silent then my other rigs, and has more than enough processing power. I also got a set up with mini ITX, and the case is only a little smaller. I am still going to build that one, cause i have most of the parts, but this case is definately the way to go for a gamer on the go, or with small space. Way better than a laptop IMHO.
