Silverstone SG07B-W Gaming SFF Case


Introduction to the Silverstone SG07W Gaming SFF Case

Today, we will be taking a look at a new small form factor case (SFF for short) from Silverstone. We have seen a few SFF cases over the years from Silverstone like the SG-06, but the new SG07 is aimed at the person who wants to be able to build an awesome gaming rig in a relatively small amount of territory.

Its ability to accommodate graphic cards up to 12.2 inches in length is what will make SG07 stand out from the others in the SFF case market. Until now there weren’t many SFF cases that gave the end-user this much leeway when it came to building their ideal gaming rig. Or one worthy enough to be hauled to local LAN parties at least. So to be able to hold on to that advantage the SG07 also comes with an 80Plus certified 600 watt power supply, easily earning it’s “Gaming SFF” title. Yes, the SG07 does offer a lot in the form of features, but there is even more to it than the small size and an 80Plus Bronze rated power supply. But we can’t give away all the juicy details in the introduction! You will have to read on to find out more.

What Silverstone has to say about the SG07W

The Sugo SG07, with a size that slots in between the venerable SG01 Micro-ATX SFF case from 2005 and the SG05, a powerful Mini-ITX case released in 2009, was designed to take the Mini-ITX platform to a whole new level. It is twice as powerful as the SG05 but only 37% bigger. Its custom 600W power supply, which is rated up to 50℃with 80 PLUS Bronze level efficiency and single +12V rail, was carefully chosen and optimized for SG07. Exhaustive testing was conducted to create unique VGA fan duct and exhaust vents that enable SG07 to not only accommodate the longest consumer graphics cards physically (up to 12.2 inches/310mm) but also capable of supporting graphics thermal profile of up to 400W through overclocking. For the CPU and motherboard area, a record-breaking use of 180mm fan (bigger than the Mini-ITX motherboard!) with vortex generating design was utilized to provide possibility of fanless CPU cooling of up to 95W (via CPU cooler such as SilverStone’s NT06-E). But despite having tremendous amount of cooling performance, the SG07 is easy to maintain as well. It employs positive pressure layout with all intake areas fitted with removable filters so dust will not accumulate inside. If the goal is to make the ultimate Mini-ITX system, the SG07 is hard to beat.

Closer look at the outside

Typically if you are planning on building a SFF gaming rig the first thing you want like to know is how big the case is, and how much it’s going to weigh in at. Well for starters the SG0-07 tips the scales at 10.8 pounds, which you might think is a typo, but keep in mind that is with the included power supply. Not too bad of a weight when taken into perspective, but we know once the components are added the weight sky-rockets.

The dimensions of the SG07 are not too bad either. Measuring 8.7 x 7.4 x 13.7 inches the SG07 is easy to transport from one place to another. Finding a bag to aid in the moving of the case should be fairly easy as well. I also found that in adding it to my collection of desktop items that the amount of real estate needed was not bad.

The SG07 as of now comes in black and is made of steel, plastic and some aluminum. We say some aluminum because the part consisting of aluminum is the face plate, while the rest of the front is made of plastic.

There is only one exterior drive bay in the SG07 and even this is for a low-profile or slim optical drive. The only other thing you’ll find on the face plate is Silverstone’s logo. There are two USB 2.0 ports and audio jacks sitting off to the far right, while the power button sits in the bottom left corner.

The rear of the SG07 does offer something you don’t see everyday as the power connector isn’t truly part of the power supply, but an extension of it (which we will get into more later). The presence of just two expansion slots lets us know that the SG07 only has support for ITX and D-ITX motherboards. We see these types of motherboards becoming more popular as Zotac, Gigabyte and even ECS produce several models of them. If you happened to notice the fact we did not mention the reset button as part of the front panel layout, then that is because it actually sits in the rear of the case above the expansion slots. To finish our tour of the SG07’s rear, the last thing to point out is a small switch that controls the speed of the fan included with the case.

Many SFF seem to have problems with air ventilation, which is primarily due to the placement of fans and its cramped quarters that limit air circulation. Silverstone tries to combat this with the use of a massive top-mounted 180mm cooling fan and is from their Air Penetrator series. This is the fan that is controlled by the switch in the rear of the case we mentioned above, limiting the fan to spin at either 700RPM or 1200RPM depending on the placement of the switch. At either speeds the fan remains decently quiet at 18 dBA and 34 dBA respectfully.

Depending on if you purchase the SG07B or SG07B-W will determine if you get windowed panels. The model we received was the B-W, as you can see by the windows in the blow photos. To aid in the cooling of the GPU a small duct can be added to the side panel, that just so happens to come with a dust filter. On the opposite side you will find it consisting of two ventilation areas. The windowed one gives you a nice view that isn’t obstructed by the video card, while the other (to it’s left) provides exhaust ventilation for the power supply.

To further help with cooling the bottom of the SG07 is equipped with a vent that lines up with the power supply fan. Four rubber feet keeps the SG07 off the surface and finally another small vent that is located under the PCIe x16 slot.

Closer look at the inside

Removing three screws allows the user to remove the outer shell from the case’s frame. All three sides are one solid piece, eliminating the need to remove several screws and thne three individual panels. Once open you see the inside is fairly spacious in the rear of the case but somewhat crowded upfront.

Upfront are a total of three cages each serving a different purpose. The top cage is home to the one optical drive, with the second cage housing a single 3.5” drive on the top and two 2.5” drives on the underside. Ideal for those that want to raid a couple of solid state drives and have a standard mechanical drive for storage purposes. The yellow pieces you see are rubber vibration eliminators. On case bottom is where the 600W power supply is mounted.

Speaking of the power supply, Silverstone made this model specifically for SFF enclosures by giving it shortened and sleeved cables. The unit is strong enough to support GPUs up to 400 watts and this includes the Nvidia GTX 480 and Radeon HD 5970. It is capable of providing an impressive 552 watts on the single 12 volt rail. The SG07 uses a small extension to link the PSU to the power plug on the rear of the case. Chances are you probably have never seen a SFF case come with such an impressive power supply as in this case.

Here we have a better shot of the 18cm Air Penetrator intake fan that is the heart of the SG07 ventilation. The way the grill and blades are setup helps to focus a greater amount of air to overcome any obstacles. Because of the small form factor of the case you are limited to what CPU cooler you can use, so the Air Penetrator assists the heatsink to be more effective. From the top looking down you see the fan comes equipped with a air filter to help keep dust under control.


The majority of the SFF cases I have used have all been a bit tricky to work with. After all it is nearly impossible to make one not be given the small confines you have to work in. As much as we like the SG07 it even offered up challenges in some areas as well. One was cable management, but that comes with the territory for cases of this size. At the end of the build we had cables all over the place. We did manage to get everything installed in it though.

We decided to pack the SG07 with as much as possible, while not eliminate anything from the case. We could have easily left the 180mm fan from the build to make room for a larger cooler but we felt the fan was a big part of this case’s features.

Test Hardware:

  • Motherboard:Gigabyte H55N-USB3
  • Processor: Intel Core i5 655K
  • Ram: OCZ DDR3 1600 4GB Dual Channel
  • Video Card: ASUS Radeon HD 5870
  • HDD: Western Digital 320GB Black Scorpion, Patriot 128GB Torqx, Western Digital 2TB Green
  • Power: Silverstone 600W
  • Case: Silverstone SG07B-W
  • Cooling: Intel Stock 1156
  • OS: Microsoft Windows 7 64-bit

It begins with the motherboard placement to see if everything lines up correctly and make sure there aren’t any clearance issues. No problem there.

Next we removed the drive bay cages in order to get the drives all in place. In the image below we have almost 2.5TB of space in such a small area. The 2.5” drives only need two screws to secure them while the bigger and heavier 3.5” requires the typical four screws to hold them in.

The optical drive is mounted into its own tray, and requires four very small screws to attach it. In order to get the drive to fit properly in the enclosure the plastic bay cover must be removed.

After finally bolting the motherboard to the tray of the we attached the CPU cooler, seated the RAM and made all the connections that needed to be made. Afterward we slid the Radeon HD 5870 through the side of the enclosure, but had to so at an angle in order to fit it through the frame. All went well and this is where we were beginning to feel that we have the ultimate SFF case.

After all that is done what we had left was a nice gaming rig with a web of cabling going everywhere. Taking a little more time in the build would resort in less of a mess but we were just too excited to get the rig up and running!

Below you see one of the very few issues we found with the SG07. That L-shaped metal piece covering the screw hole for the expansion slots that is intended to be used as a hold down (or retention mechanism if you rather), actually can not be used due to the way the bracket of the GPU is manufactured. So instead we forewent it’s usage and simply put a screw through as you typically would have.


We ran a series of applications just to see how cool the SG07 could keep a working system. OCCT, GPU-Z Core Temp and HWMonitor were all utilized for the testing. We ran OCCT for twenty minutes to put a load on the CPU, GPU and Power Supply. Temperatures were recorded using GPU-Z, Core Temp and a digital multi-meter.

The Silverstone SG07 is a very impressive case when you factor in the size. Many would consider the SG07 just a small form factor case without having an opportunity to see it in person. Yes, I was one of those people. Yet after spending a few days with it I now place it in a category that only a few cases can be considered: small gaming form factor.

What justifies a case of this size to qualify as a SGFF? Well, it being able to accommodate both a high-end graphics card, like the Radeon HD 5970 or Nvidia GTX 480, in addition to a power supply capable of providing enough power to said graphics card is a good start; the SG07 does both of those. Already being equipped with its own 80PLUS Bronze certified 600W power supply sure makes for a good argument too.

If you are worried about ventilation then you really mustn’t. The SG07 comes packing a huge top-mounted 180mm Air Penetrator fan for an intake. Then there are plenty of areas throughout the case to allow for that hot air to escape.

These are just a few of the many extras that set the Silverstone SG07 apart from other smaller cases, as we have hopefully pointed out well enough during the course of the review. However, there are a few things that end up making a build using a case like this. First would be finding a good motherboard to build around. We choose the Gigabyte H55N-USB3 as it is one of the best overclocking ITX motherboards out there, but as they are upgraded more frequently than a case typically is, you may encounter that finding a suitable board at a later date may prove to be a bit daunting.

Some research will be needed to find the right cooler for you and this case. Silverstone does offer a couple of coolers that will fit into the SG07, but if you decide to go with another manufacturer check your measurements first.

Lastly, we get to the optical drive. Be prepared to fork out a few more dollars for a slim-line optical DVD or Blu-Ray drive. (Editor’s Note: While I agree since a new one would not be cheap, as this is your standard size laptop drive you can find all kind of them on eBay, like the Dual-Layer DVD burner for $12.49 that I just did. Though keep in mind the trim piece for the tray will be tailored to whatever laptop they come from, if you can find a flat replacement or mod something then you’d be set.)

The SG07 will set you back about $200 from online stores like Amazon. It may seem like a lot of money but you have to consider what you are getting. A well built small form factor case that you can put in the gaming rig you always wanted, a stout 600W 80+ Bronze class power supply, and all from a quality company like Silverstone. ‘Nuff said.
