The Grandia GD05 is a follow-up of the incredible GD04 as a chassis that combines years of SilverStone expertise in SFF (Small form factor) and HTPC (Home Theater Personal Computer) designs. It has the same beautifully proportioned exterior and powerful thermal capability that rivals the best tower chassis. However, the front panel of the GD05 was designed to be more flexible so that its 325mm depth can be utilized in more places than just home theaters. Even though GD05s 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 device, two 3.5 hard drives, a 2.5 SSD, a standard ATX power supply, and two high-end graphics cards up to 11 inches. Cooling duty in the GD05 is handled by three filtered 120mm fans designed with the same positive air pressure to enable 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 special attention given to the order of installation, any user can quickly assemble or upgrade the GD05 with a small and powerful PC system. - Three silent 120mm fans included- Positive air pressure design for excellent cooling/quietness and dust-prevention- Beautiful aluminum skin for classic appearance- Incredible 325mm depth to fit comfortably inside home theater cabinet- Designed with cable routing for easy installation- Supports power supply up to 180mm long- Support expansion cards up to 11 inches- Support 2.5 hard drive or SSD (Solid-state drive)- Material: Aluminum skin over plastic front panel, 0.8mm SECC body- Motherboard: Micro-ATX, DTX, Mini-ITX- Drive Bays: External 5.25\" x 1 / Internal 3.5\" x 2 , 2.5 x 1 or 3.5\" x 1 , 2.5 x 2- Rear Cooling: 2 x 80mm fan slots (optional mounting)- Side Cooling: Right: 2 x 120mm intake fans, 1200rpm, 20dBA / Left: 1 x 120mm intake fan, 1200rpm, 20dBA- Expansion Slots: 5- Front I/O Port: USB 3.0 x 2 / audio x 1 / MIC x 1- Power Supply: Support standard PS2(ATX)- Expansion Cards: Support graphic cards up to 11 inches.- Limitation of CPU cooler: 70mm (remove ODD if you want install up to 120mm)- Limitation of PSU: 180mm (remove Left fan replacement as 80mm if you want install up to 220mm)- Dimensions: 440 mm (W) x 151 mm (H) x 325 mm (D)
