As a new edition of The Tower Series, The Tower 300 inherits the classic vertical case design but comes in an octagonal prism shape. It has amazing hardware compatibility, accommodating a 4090 GPU, a standard-sized power supply up to 220mm, and a 420mm AIO radiator. What's more, it can accommodate up to eight 120mm/140mm fans on the top, back, PSU cover and right side fan bracket. If you want to make The Tower 300 more visually appealing, you can purchase the separately sold 3.9" LCD Screen Kit and Chassis Stand Kit to upgrade the build; the former to display real-time component information and the latter for a unique view with a special horizontal placement. •P/N: CA-1Y4-00S1WN-00 •SERIES: The Tower •CASE TYPE: Micro Tower •DIMENSIONS: 551 x 342 x 281 mm (22.5 x 14 x 11.5 inch) •WEIGHT: 8.3 kg / 18.3 lbs. •SIDE PANEL: 3mm Tempered Glass x 1 •COLOR: Black •MATERIAL: SPCC •COOLING SYSTEM: Top(exhaust):140 x 140 x 25 mm CT140 fan (1500rpm •EXPANSION SLOTS: 4 •MOTHERBOARD: 6.7" x 6.7" (Mini ITX) •I/O PORT: USB 3.2 (Gen 2) Type-C x 1 •PSU: Standard PS2 PSU (optional) •FAN SUPPORT: Top: 2 x 120mm, 1 x 120mm, 2 x 140mm, 1 x 140mm ; Right Side: 3 x 120mm, 2 x 120mm, 1 x 120mm, 3 x 140mm, 2 x 140mm, 1 x 140mm ; Rear: 2 x 120mm, 1 x 120mm, 2 x 140mm, 1 x 140mm ; Power Cover: 1 x 120mm, 1 x 140mm •RADIATOR SUPPORT: Right Side(AIO): 1 x 360mm, 1 x 240mm, 1 x 120mm, 1 x 420mm, 1 x 280mm, 1 x 140mm •CLEARANCE: CPU cooler height limitation: 210mm ; VGA length limitation: 280mm(With power cover), 400mm(Without power cover) ; PSU length limitation: 220mm
