GIGABYTE Aorus C300G ATX Mid Tower Cabinet (Black)

The GIGABYTE Aorus C300G (model GB-AC300G) is an ATX mid tower cabinet designed to accommodate mini-ITX, Micro-ATX, and full ATX motherboards inside a sleek black steel-and-glass chassis. The full-size side panel is constructed from 4mm black-tinted tempered glass, which offers scratch and abrasion resistance while displaying your build with a subtle, low-contrast aesthetic. An enhanced frame surrounds the glass panel to reduce pressure and limit the risk of fragmentation during everyday use. The front I/O panel is a clear differentiator for this cabinet. It provides one HDMI output, one USB 3.1 Gen2 Type-C port, two USB 3.0 ports, audio in and out (supporting both AC97 and HD Audio standards), and an LED control button for managing the onboard RGB lighting — giving builders convenient access to modern connectivity at the top of the case. RGB Fusion 2.0 integration lets you synchronise lighting across compatible AORUS devices with up to 16.7 million colour options and multiple lighting effects, all controllable through GIGABYTE’s software ecosystem. Ventilation and cooling flexibility are a priority. The front panel supports up to three 120mm fans or two 140mm fans, the top accommodates two 120mm or two 140mm fans, and the rear accepts one 120mm fan. For liquid cooling, the front supports radiators up to 360mm, 280mm, or 240mm, while the rear supports a 120mm radiator — making large all-in-one or custom loop setups practical. Two fans come pre-installed (one front 120mm, one rear 120mm). GPU installation flexibility is built in: cards can be mounted horizontally in the traditional orientation or vertically using a PCIe riser cable (sold separately), with the cabinet offering seven standard expansion slots or two in vertical mode. The GPU clearance is up to 400mm in length. A PSU shroud hides the power supply and cable clutter from view while thermally separating the PSU from the rest of the system. Standard ATX power supplies up to 180mm in length are supported (PSU not included). Detachable dust filters on air intake areas are removable and rinse-cleanable for straightforward maintenance. Anti-vibration rubber feet absorb operational vibrations and aid in stability. Storage is handled by two 3.5-inch/2.5-inch combo bays and three additional 2.5-inch SSD bays mounted behind the motherboard tray, keeping the interior visibly clean and organised. No 5.25-inch optical drive bay is included. — Verified Specifications — Model: GB-AC300G | Form Factor: Mid Tower | Motherboard Support: mini-ITX, Micro-ATX, ATX | Colour: Black | Materials: Steel, Plastic, Glass | Dimensions: 469mm (L) × 211mm (W) × 458mm (H) (±1%) | Expansion Slots: 7 (horizontal) / 2 (vertical, PCIe riser required) | 3.5″/2.5″ Combo Bays: 2 | 2.5″ SSD Bays (rear): 3 | 5.25″ Bays: None | I/O: HDMI ×1, USB 3.1 Gen2 Type-C ×1, USB 3.0 ×2, Audio In/Out (AC97/HD Audio) | Fan Support: Front 120mm ×3 / 140mm ×2, Top 120mm ×2 / 140mm ×2, Rear 120mm ×1 | Radiator Support: Front 360/280/240mm, Rear 120mm | Max CPU Cooler Height: 170mm | Max GPU Length: 400mm | Max PSU Length: 180mm | PSU Type: Standard ATX (not included) | Warranty: 1 Year
