PC Case Thermaltake Ceres 300 TG Midi Tower Green

The Thermaltake Ceres 300 TG ARGB Mid Tower Chassis is an ATX-compatible mid-tower PC case in green that emphasizes airflow and expandability. It ships with two CT140 ARGB PWM fans pre-installed at the front and one CT140 PWM fan at the rear, a 4 mm tempered glass left-side panel, removable dust filters, and support for multiple radiator and fan configurations. The case supports Mini-ITX, Micro ATX, ATX and EATX motherboards and accommodates 2.5" and 3.5" storage drives while keeping a bottom-mounted power supply layout for efficient space use.

Advantages

The chassis offers more than 55% perforated panels to maximize intake and exhaust airflow and comes with three pre-installed 140 mm fans to provide immediate cooling out of the box. RGB lighting on the included CT140 ARGB fans is compatible with ASUS, GIGABYTE, MSI and ASRock motherboard software for synchronized effects. The tempered glass side panel provides a clear view of internal components, and removable dust filters on the top, front, bottom and sides simplify maintenance.

Suitable for

• Gaming and high-performance desktop builds requiring strong airflow
• Systems using liquid cooling with up to 360 mm radiator at the front and up to 280 mm at the top
• Builds needing flexible GPU orientation (vertical or horizontal) and space for large GPUs up to 370 mm (without radiator)

How to use

Install the motherboard and power supply according to the standard ATX/Midi Tower layout, placing the power supply in the bottom compartment. Mount storage drives in the dedicated 2.5" or 3.5" bays and connect case front-panel cables to the motherboard. Configure fan and ARGB connections to the motherboard headers or compatible controller; ARGB lighting can be synchronized using ASUS, GIGABYTE, MSI or ASRock software. When installing liquid cooling, plan radiator placement up front (up to 360 mm) or at the top (up to 280 mm) and verify clearance for CPU cooler height and GPU length before securing components.

Recommendations

For best thermal performance, keep front perforated panels unobstructed, use the included CT140 fans as intake with the rear fan as exhaust, and clean the removable dust filters regularly. When using a vertical GPU mount, ensure compatibility of your riser cable and standoffs and verify airflow around large radiators to maintain stable internal temperatures.
