Silverstone Sugo SST-SG07 600W
Silverstone recently updated the Sugo SG07, which is the second-most expensive chassis in this test. Part plastic, part aluminium, the front panel looks cool. On the right there are two USB 3.0 ports and audio connectors. There is lots of space inside thanks to the clever lay-out. The integrated 600-watt 80 Plus Bronze SFF power supply is located in the front.
You can fit most common dual-slot graphics card, one 3.5-inch or two 2.5-inch hard disks/SSDs and a slimline optical drive. Cooling is provided by a very effective 180 mm fan. This is the only chassis that kept temperatures far below 30 degrees, which makes it the best choice if you want to build a high-end Mini-ITX system. When the fan is turning a high speed, it's not that quiet anymore, but the cooling is fine at low speed. £149 is a lot of money, however, even with the powerful PSU included.
