Micro-ATX Tower for Compact Builds

The Tower 300 Bubble Pink is a Micro-ATX chassis finished in pink with an octagonal prism profile. It accepts Mini-ITX and Micro-ATX motherboards and includes two pre-installed 140mm CT fans at the top. Three tempered glass panels on the front, left and right provide full visibility of the interior. Builders wanting a distinctive vertical layout in a smaller footprint will find the layout practical.

Upgrade from Standard Mid-Tower Layouts

The case replaces conventional rectangular mid-towers by moving the radiator mount to the right side panel, allowing a 420mm or 360mm AIO directly in front of the motherboard tray. GPU clearance reaches 400mm when that side radiator is omitted, but drops to 280mm with a radiator installed. The jump is worth it when a high-end liquid loop matters more than maximum graphics card length.

Sustained Thermal Behaviour Under Load

Eight fan positions across the top, rear, right side and bottom support 120mm or 140mm units for balanced intake and exhaust. The right-side radiator mount handles 120mm, 140mm, 240mm, 280mm, 360mm or 420mm radiators, keeping coolant temperatures steady during extended sessions. CPU cooler height is capped at 210mm and power supply depth at 220mm, so component choice stays within those limits for consistent airflow.

Questions about this item

What motherboard form factors fit inside the Tower 300 Bubble Pink?

The case accepts Mini-ITX boards measuring 6.7 by 6.7 inches and Micro-ATX boards measuring 9.6 by 9.6 inches.

How do the two pre-installed CT140mm fans mount, and what step is often missed?

They ship already screwed into the rear panel; the step many builders forget is connecting both fan headers to the motherboard or a hub before closing the side glass.

Which dust filters will need cleaning or replacement over time?

Magnetic filters cover the top, bottom and right-side intake areas; they slide out for rinsing and should be checked every few months.
