The SX-3140 NORMAL CASING is a straightforward, budget-friendly computer case built for essential computing needs. Designed for offices, schools, cyber cafes, and home users who prioritize function over flash, this casing provides a sturdy, reliable enclosure for standard ATX components without unnecessary frills or premium pricing.

Practical Design for Everyday Use
The SX-3140 features a clean, professional black exterior that blends seamlessly into any environment — whether under a desk in a corporate office, in a school computer lab, or in a home study corner. The solid metal side panel (non-tempered glass) offers durability and EMI shielding, while the front panel includes easy-to-access USB and audio ports for connecting peripherals and headsets.

Standard ATX Compatibility
Supporting full ATX, Micro-ATX, and Mini-ITX motherboards, this case accommodates a wide range of system builds. With 7 expansion slots, you can install multiple graphics cards, sound cards, or network adapters as needed. The drive bay configuration includes two 5.25" external bays for optical drives (DVD/CD-RW) — still useful in many office and archival environments — plus internal bays for 3.5" HDDs and 2.5" SSDs.

Adequate Cooling for Basic Systems
While not designed for high-performance gaming, the SX-3140 provides sufficient airflow for standard office and home PC configurations. Ventilation openings on the front, rear, and side panel allow passive heat dissipation. Optional fan mounts at the front (120mm) and rear (80mm/92mm) let you add active cooling if your system requires it. A rear exhaust fan is often pre-installed for basic airflow out of the box.

Easy Assembly and Maintenance
The tool-less or screw-based design (depending on revision) allows straightforward installation of motherboards, power supplies, and drives. Removable drive cages and ample interior space make cable management acceptable for non-modular power supplies. The case includes all necessary screws, standoffs, and a basic speaker/buzzer for POST beep codes.

Durable Steel Construction
Built from cold-rolled SPCC steel, the SX-3140 resists flexing and provides solid protection for internal components. The powder-coated finish resists scratches and fingerprints, keeping the case looking professional for years.
