The Grandia GD04 is an incredible product that combines years of SilverStone's expertise in SFF (Small form factor) and HTPC (Home Theater Personal Computer) chassis design. It has a beautifully proportioned exterior and powerful thermal capability that rivals the best tower chassis. From the front, the GD04 is shaped similarly to most home theater components, but the depth was reduced to a mere 323mm. This overall size of 21.5 liters in volume actually makes the case one liter smaller than SilverStone's own Micro - ATX Sugo cases! Even though GD04's diminutive size allows it to easily integrate into any home theater cabinet, it can still accommodate an impressive list of standard components such as 5.25-Inch optical drive, two 3.5-Inch hard drives, a 2.5-Inch SSD, a standard ATX power supply, and two high - end graphics cards up to 11 inches. Cooling duty in the GD04 is handled by three filtered 120mm fans designed with the same positive air pressure as the Fortress FT01, this enables class - leading cooling efficiency, reduced dust buildup, and silent operation. To make installation simpler, there is even enough space for cable management to be easily accomplished without the need for short cabled or modular power supply. Coupled with the special attention given to the order of installation, any user can quickly assemble or upgrade the GD04 and devote more time to enjoying a personalized digital life with an HTPC. Now updated with USB3.0 ports.
