Exterior
The exterior of the Thermaltake Tower 250 Hydrangea Blue Mini Tower Chassis is a bold fusion of style and compact engineering. Its octagonal prism shape sets it apart from traditional rectangular cases, offering a sleek vertical silhouette that minimizes desk space while maximizing airflow. The Hydrangea Blue finish adds a vibrant, refreshing touch to any setup, making it a standout centerpiece for builders who value aesthetics. Three 3mm tempered glass panels on the front provide a panoramic view of internal components, while two perforated side panels enhance ventilation and visual symmetry. The overall design is clean, modern, and purposefully structured to balance form and function.
Customization is a key part of the Tower 250’s exterior appeal. Users can opt for the separately sold Chassis Stand Kit, which allows horizontal placement for a unique viewing angle and alternative layout. The top panel houses a well-integrated I/O section with USB 3.2 Gen 2 Type-C, dual USB 3.0 ports, and audio jacks, all easily accessible without disrupting the chassis’s streamlined look. Whether standing tall or laid flat, the Tower 250 Hydrangea Blue offers a visually engaging and highly adaptable exterior that complements both minimalist and expressive build styles
Interior
Inside the Thermaltake Tower 250 Hydrangea Blue Mini Tower Chassis, you’ll find a surprisingly spacious and modular layout tailored for Mini-ITX builds. Despite its compact footprint, the case supports high-end components including GPUs up to 360mm (without the PSU cover), CPU coolers up to 210mm in height, and ATX or SFX power supplies up to 200mm. The interior is designed with flexibility in mind, featuring a removable fan bracket on the right side that accommodates up to three 120mm or two 140mm fans—or a 360mm/280mm AIO radiator for advanced cooling setups. Behind the motherboard tray, users can install up to two 2.5″ SSDs or one 3.5″ HDD, keeping storage neatly tucked away without cluttering the main chamber.
Thermal performance is a core strength of the Tower 250’s interior design. It comes pre-installed with two CT120 PWM fans at the top, and offers additional mounting points on the PSU cover and rear panel for further airflow customization. The vertical layout promotes natural heat dissipation, while strategically placed cold air intakes and hot air exhausts maintain low internal temperatures. Dust filters on the top, rear, inner sides, and bottom layer help preserve system cleanliness over time. With Thermaltake’s Dismantlable Modular Design, every panel and bracket is easily removable, making installation and upgrades refreshingly straightforward even in such a compact chassis.
Closer Look
Taking a closer look at the Thermaltake Tower 250 Hydrangea Blue, it’s clear this chassis is designed to be both visually striking and functionally robust. Its vertical octagonal prism shape isn’t just for aesthetics—it minimizes desk footprint while maximizing internal space. The three tempered glass panels on the front offer panoramic views of your build, ideal for showcasing high-end components and RGB setups. Tool-free access to these panels makes maintenance and upgrades refreshingly simple. The case supports Mini-ITX motherboards and accommodates GPUs up to 360mm (without the PSU cover), CPU coolers up to 210mm, and ATX or SFX power supplies up to 200mm, giving it serious flexibility for a compact form factor.
Cooling is where the Tower 250 really flexes. It comes pre-installed with two CT120 PWM fans on the top and supports up to eight 120mm or five 140mm fans throughout the chassis. The right side features a removable bracket for mounting a 360mm or 280mm AIO radiator, while additional fan mounts on the rear and PSU cover allow for tailored airflow setups. Dust filters on all major intake and exhaust points—including the top, rear, sides, and bottom—help keep the internals pristine. For those who want to personalize their build even further, Thermaltake offers optional accessories like a 3.9″ LCD screen kit for real-time system monitoring and a chassis stand kit for horizontal placement.
