Description

The Thermaltake The Tower 300 Bubble Pink redefines the Micro-ATX form factor with its distinctive vertical octagonal prism silhouette. This chassis provides a panoramic view of internal components through three 3mm tempered glass panels, blending aesthetic elegance with high-performance thermal capabilities. Its compact footprint makes it ideal for desk-centric setups without sacrificing compatibility for high-end hardware.


This product is for:
- PC Enthusiasts seeking a unique vertical "showcase" aesthetic for their desk.
- Content Creators who require high-performance cooling for intensive rendering in a compact space.
- Gamers looking to fit large GPUs (up to 400mm) within a Micro-ATX footprint.
- Aesthetic-focused builders prioritizing the "Bubble Pink" color scheme for themed setups.
- Small Form Factor (SFF) builders who want the thermal headroom of a 420mm AIO.

- Motherboard Support: Mini-ITX (6.7" x 6.7"), Micro-ATX (9.6" x 9.6")
- Cooling Support: Right side up to 420mm AIO; Top/Right/Rear/Power Cover fan mounts
- Clearance: CPU Cooler height 210mm; VGA length 280mm (with cover) / 400mm (without)

Building in The Tower 300 is a streamlined experience thanks to its modular design and vertical airflow path. The chimney effect naturally exhausts heat through the top-mounted CT140 fans, while the right-side intake accommodates massive 420mm radiators for superior CPU cooling. Users can further customize the display by purchasing an optional horizontal stand, transforming the vertical tower into a unique console-style showcase.

Compared to traditional Micro-ATX cases like the Cooler Master Q300L, The Tower 300 offers significantly better vertical clearance for tall air coolers (210mm) and larger radiator support (420mm vs 240mm). While it occupies a taller vertical space, its footprint is narrower than dual-chamber cases like the Lian Li O11 Dynamic Mini, making it better suited for narrow desks.

Q&A:
- Does The Tower 300 support the NVIDIA RTX 4090? Yes, it supports GPUs up to 400mm in length when the power cover is removed.
- Can I mount the case horizontally? Yes, but it requires a separate horizontal chassis stand accessory sold by Thermaltake.
- What is the maximum radiator size supported? The right side of the chassis supports radiators up to 420mm or 360mm.
- How many fans are included with the case? It comes pre-installed with two CT140 140mm fans at the top.
- Is the USB-C port high speed? Yes, the front I/O includes a USB 3.2 (Gen 2) Type-C port for fast data transfer.
