Product information

Description

PHANTEKS Eclipse P400A is a black Midi Tower PC case featuring a full metal mesh front panel and three preinstalled 120 mm front fans. The Ultra-Fine Performance Mesh design improves airflow while reducing dust intake to maintain cooler internal temperatures for CPU and GPU components. The case supports a wide range of motherboard form factors including ATX, Micro-ATX, Mini-ITX and E-ATX, offers a rear 120 mm fan mount and a bottom-mounted power supply layout, and provides storage capacity for two 3.5" drives and two 2.5" drives. Front I/O includes two USB 3.2 Gen 1 Type-A ports for high-speed peripheral connections. Overall external dimensions are 210 × 465 × 470 mm.

Advantages

The mesh front and Ultra-Fine Performance Mesh maximize airflow for effective cooling of system components while limiting dust ingress. Three preinstalled 120 mm front fans provide immediate intake airflow out of the box, reducing the need for additional fans. Compact Midi Tower dimensions combined with broad motherboard support allow flexible system builds from Mini-ITX to E-ATX. Steel and mesh construction offers structural rigidity and reliable mounting points for drives, fans and cooling solutions. Two front USB 3.2 Gen 1 ports deliver convenient fast data transfer and peripheral connectivity.

Suitable for

Air-cooled gaming or workstation builds that require strong front intake airflow
System builders who need support for ATX, Micro-ATX, Mini-ITX or E-ATX motherboards
Users planning a combination of 3.5" HDDs and 2.5" SSDs for mixed storage
Compact desktop setups where a Midi Tower footprint with good cooling is desired

How to use

Install the chosen motherboard into the standoffs that correspond to its form factor and secure it with screws. Mount the power supply in the bottom compartment and route power cables through the provided openings. Install 3.5" or 2.5" drives into the dedicated trays or mounting points, and connect SATA power and data cables to the drive and motherboard. Fit cooling components such as the CPU cooler and any additional fans, ensuring airflow direction aligns with the front intake and rear exhaust design. Use the front I/O ports for connecting USB peripherals. Close panels and verify cable management to maintain unobstructed airflow through the Ultra-Fine Performance Mesh.

Usage recommendations

For best thermal performance, maintain unobstructed airflow by keeping cables tidy and using the three preinstalled front fans as intake with a rear exhaust fan. Regularly clean the mesh front panel to reduce dust buildup and preserve cooling efficiency. When planning an E-ATX or tall CPU cooler build, verify component clearance against the case dimensions and mounting points before assembly.
