Introduction
When building a PC, the case is often an afterthought for many enthusiasts. However, choosing the right case – especially when space is at a premium – can make or break your build. Enter the world of smallest ATX cases: compact powerhouses that offer full-size compatibility without dominating your desk space.
ATX (Advanced Technology eXtended) is a motherboard form factor specification introduced by Intel in the 1990s. An ATX case is designed to accommodate ATX motherboards while potentially supporting smaller form factors like micro-ATX and mini-ITX. The challenge lies in finding cases that support full ATX boards while minimizing overall size.

- Portability: Easier to transport for LAN parties or office moves.
- Aesthetic Appeal: A sleek, minimalist look that fits modern decor.
- Forced Optimization: Encourages thoughtful component selection and cable management.

Cooling Considerations for Small ATX Cases
Efficient cooling is crucial in compact builds. Consider these tips:
- Fan Configuration: Aim for positive air pressure with more intake than exhaust fans.
- Liquid Cooling: AIO coolers can be a space-efficient cooling solution.
- Airflow Optimization: Remove unused drive cages and use cable combs to improve airflow.
- Fan Quality: Invest in high-quality, static pressure-optimized fans for better performance in restricted spaces.

Building in a Small ATX Case
- Plan Your Build: Carefully consider component placement before assembly.
- Install CPU and RAM: Mount these on the motherboard before case installation.
- Manage Cables as You Go: Route cables immediately after installing each component.
- Consider Custom-Length Cables: Shorter cables reduce clutter in tight spaces.
- Be Patient: Building in a compact case requires more time and attention to detail.
