Computer Chassis




How much performance and components 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 of 23 liters, 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 via relocation to motherboard backside mounting, the SG09 can accommodate two 13.3 inches (337mm) long graphic 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 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 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.

    * If you intend to utilize all hard drive slots, please remove all unused power supply cables.
       These unused cables may cause problem with the installation. SSDs are highly recommended in place of hard drives.

    * Maximum length for PSU is 180mm, we recommend 160mm due to varying connector locations on PSUs and the unique structure of SG09.
       We do not promise that all retail PSUs on the market can be installed in the SG09. Please refer the guides provided in this manual to select your PSU.
