Frequently asked questions
- How do I know a case fits my components?
- Check the supported motherboard sizes along with the maximum graphics card length, CPU cooler height and radiator clearance. Comparing these figures against your parts avoids compatibility problems.
- Is airflow or a quiet design more important?
- Mesh-fronted cases prioritise airflow and lower temperatures, while solid panels favour quieter operation. The right choice depends on how powerful and how quiet you want the system to be.
- Do PC cases come with fans?
- Some cases include one or more pre-installed fans, while others leave the mounts empty for you to add your own. Check what is supplied so you can budget for extra cooling if needed.
