Thermaltake Tower 300 Bumblebee Micro-ATX Case CA-1Y4-00S4WN-00

Micro-ATX Tower for Showcase Builds

The Tower 300 Bumblebee is a Micro-ATX chassis finished in a distinctive yellow-and-black colour scheme. It accepts Mini-ITX and Micro-ATX motherboards, making it suited to compact high-performance systems. Three panels of 3 mm tempered glass on the front, left and right sides give a clear view of internal components. The case ships without a power supply, so the builder provides their own unit.

Cooling Limits With Radiator Placement

A 420 mm or 360 mm radiator can be mounted on the right side in front of the motherboard tray, but doing so reduces the maximum graphics card length from 400 mm to 280 mm. Without a side radiator the full 400 mm GPU clearance is available. The CPU cooler height limit is 210 mm and the power supply compartment accepts units up to 220 mm long. Two 140 mm fans are pre-installed at the top.

Glass Panels and Port Layout

Three tempered-glass panels mean fingerprints are visible and regular cleaning is needed for a pristine look. The front I/O cluster provides one USB 3.2 Gen 2 Type-C port, two USB 3.0 ports and a single audio jack. Three internal 3.5-inch bays and three 2.5-inch bays offer storage flexibility, while four expansion slots support full-height add-in cards. The bottom-mounted power supply layout keeps cables tucked away.
