SilverStone Sugo SG09
The Sugo design has evolved greatly from the original SG01, but still fits within SilverStone's design principles. The SG09 is meant to still be a SFF enclosure but to offer a lot of potential by allowing up to two 13.3-inch graphics cards to be installed, a full tower CPU cooler, and up to six disk drives. Should you be going for a performance build in this compact 23 liter chassis, there is plenty of cooling opportunities, especially with the pre-installed Air Penetrator 180mm fan at the top of the chassis.
On the front of the chassis are two USB 3.0 ports, audio input/headphone jacks, and the usual front panel power/reset switches and LEDs. Occupying the top half of the front panel is also a detachable PSU fan filter, since with the SG09 the power supply is located at the front of the system. At the very top of the chassis is also the enclosure's lone slim optical drive bay. Of course, with many Linux users using USB-based OS installations and other Internet downloads for software, not many Phoronix readers will need to worry about the optical drive bays. The front panel for this case is made of plastic while the rest of the body is comprised of steel.
On the left side panel there is a honeycomb ventilation area that aligns with the case's unique power supply mounting area. At the bottom of the side panel is a pre-installed 120mm 22 dBA fan as well as two fan slots for installing additional 80/92mm fans. Fortunately, these three intake fan areas are covered by a fan filter. The opposite side panel offers additional ventilation too in the lower-front corner.
The AP181 Air Penetrator fan at the top switches between 700 and 1200 RPMs for 18 and 34 dBA noise levels. The fan speed is adjusted at the back of the case with a simple switch between low and high levels.
At the back of the case the 120mm (22 dBA) exhaust fan can be seen along with the two Kensington Lock slots, I/O panel, and four expansion slots. With the power supply being mounted at the front of the system, there's also an AC power connector at the back of the system that then attaches to the power supply internally.
