THERMALTAKE Tower 300 MATX Micro Tower Cabinet ( Racing Green )

The Thermaltake Tower 300 (Racing Green) is a Micro Tower chassis from Thermaltake's The Tower Series, built around a distinctive octagonal prism silhouette that keeps a compact footprint on your desk while offering serious hardware compatibility. The chassis carries part number CA-1Y4-00SCWN-00 and accommodates both Mini-ITX (6.7" × 6.7") and Micro-ATX (9.6" × 9.6") motherboards, giving builders flexibility whether they are assembling a tight gaming rig or a compact workstation. Cooling headroom is a highlight of this design. The right side fan bracket supports a 420mm AIO radiator — as well as 360mm, 280mm, 240mm, 140mm, and 120mm alternatives — so demanding CPU coolers have ample room to breathe. For air cooling, the case accommodates up to eight 120mm or 140mm fans distributed across the top, right side, rear, and PSU cover positions. Two pre-installed 140 × 140 × 25 mm CT140 exhaust fans sit at the top, rated at 1,500 RPM and 30.5 dBA, ready to move heat out of the chassis from day one. GPU builders will appreciate the generous VGA length clearance: up to 400mm without the PSU cover in place, or 280mm with it installed. CPU coolers up to 210mm in height are supported, and the PSU bay accepts standard PS2 units up to 220mm in length. Four expansion slots handle multi-slot GPU and accessory cards. Three 3mm tempered glass panels on the front let you showcase your build, while the tool-free removable panels on each side simplify maintenance. The Racing Green colorway gives the chassis a bold, distinctive look that stands apart from typical black or white offerings. Storage options include three 3.5-inch or three 2.5-inch drive bays. The front I/O panel provides a USB 3.2 Gen 2 Type-C port, two USB 3.0 ports, and an HD Audio jack — a practical selection for modern peripherals. Optional upgrades sold separately include a 3.9-inch LCD Screen Kit for real-time component monitoring and a Chassis Stand Kit for horizontal placement.
