PC Case Antec Performance 1 M Aventurine Mini Tower Black

The Antec Performance 1 M Aventurine Mini Tower Black is a compact PC case engineered for efficient cooling and straightforward assembly. It supports SFX and SFX-L power supplies mounted at the rear, offers perforated panels for improved airflow, and accommodates both 120mm and 140mm fans at the bottom. The case features aluminum side panels and an aluminum rear frame combined with a fully CNC-machined chassis for a durable, refined metallic finish and reliable construction. With support for ITX motherboards and a 2.5" drive bay, this mini tower is designed to fit powerful components in a small footprint (175 × 424 × 260 mm).

Advantages

Perforated panels provide optimized airflow while maintaining a minimalist appearance. The adjustable central mount increases compatibility with a wide range of GPU lengths and CPU cooler sizes. Tool-free side panels allow quick access for upgrades and maintenance. The chassis supports large GPUs and both 120mm and 140mm fan configurations, and the aluminum elements deliver a durable, premium look without adding excessive weight.

Suitable for

• Compact ITX gaming builds that require support for large GPUs
• Small-form-factor workstations where efficient cooling is needed
• Systems using SFX or SFX-L power supplies
• Users who prefer easy access for upgrades and maintenance

How to use

Install an ITX motherboard and mount an SFX or SFX-L power supply at the rear. Use the adjustable central mount to position your GPU and CPU cooler to achieve the best fit and clearance. Fit 120mm or 140mm bottom fans as needed to improve airflow through the perforated panels. Open the tool-free side panels to access internal components for installation or maintenance.

Recommendations

For optimal cooling and noise balance, install at least one bottom fan (120mm or 140mm) and ensure cables are routed cleanly to maintain unobstructed airflow through the perforated panels. Verify GPU length and CPU cooler height against the adjustable central mount before final assembly.
