What Is a Computer Case and How Do I Choose One?A computer case (or chassis) houses and protects your PC’s internal components such as the motherboard , CPU , GPU , storage , and power supply . Modern cases use steel or aluminum construction with tempered-glass panels, enhanced airflow routing, and support for large GPUs and advanced cooling systems. Before choosing a case, always check GPU clearance, CPU cooler height, radiator support, and compatibility with ATX 3.1 / 12V-2x6 power supplies. Case sizes come in three major formats:
Want to dig deeper into case sizes, form factors, and build-compatibility recommendations? Check out the full guide on Newegg Insider – Computer Case Size Buying Guide for a technical overview and detailed advice on choosing the right chassis for your build. In 2025, as GPUs and cooling systems continue to increase in size, selecting the right case ensures proper airflow, thermal efficiency, and upgrade flexibility. PC Gaming Cases Offer Optimal Cooling and ExpansionFor high-performance gaming builds, a gaming case offers superior airflow, expansion, and component clearance. Many modern gaming cases provide:
Smaller microATX and mini-ITX cases remain popular for portable setups, offering vertical GPU mounts, removable drive cages, and edge-to-edge glass panels for clean, modern layouts. | HTPC Cases for a Clean Home Theater SetupAn HTPC media center case is ideal for living-room entertainment PCs or compact desks. These cases typically include:
Server Chassis and Industrial CasesBusinesses and data centers rely on robust server chassis designed for reliability and scalability. Options vary depending on deployment needs:
Rackmount systems enable easier cable management and modular expansion for enterprise environments. Benefits of an ATX Case for Your BuildATX cases remain the most versatile option for gaming, workstation, and content creation systems. They offer:
Whether building a 4K gaming PC or an AI-focused workstation, ATX cases offer long-term upgrade flexibility.

Browse enclosures with tempered glass, mesh airflow fronts, RGB lighting, and liquid-cooling support to find the perfect chassis for your next build. |
Many modern mid-tower and full-tower cases support full-size ATX motherboards and 360mm AIO radiators. Check radiator mounting locations (top, front, or side) and ensure there's enough clearance above RAM and VRM heatsinks.
RGB compatibility depends on the connector. Fans using 3-pin 5V ARGB or 4-pin RGB headers generally work with ASUS Aura Sync, MSI Mystic Light, and other motherboard utilities.
Some cases include vertical PCIe slots, but others require a separate riser cable. Ensure your GPU has proper airflow when mounted vertically.
Many mid-tower cases support up to two or three 140mm fans in the front, and one or two on top. Check the case’s fan compatibility chart for exact mount options.
A high-airflow case typically features a mesh front with wide ventilation channels. Solid or glass front panels may look cleaner but tend to restrict airflow.
Montech focuses on airflow and value, while NZXT emphasizes clean aesthetics and build quality. Always compare specific model reviews rather than relying solely on brand reputation.
Mesh-front cases generally offer far superior airflow than glass-front models, especially for high-wattage components.
A case with deep cable-routing space, rubber grommets, and Velcro straps usually offers better cable management.
Solid fronts typically restrict airflow, making mesh-front cases a better choice for systems with powerful GPUs and CPUs.
Silent cases use thicker steel and sound-damping materials, while mesh cases prioritize airflow and may be noisier.
Look for cases with mesh fronts, multiple pre-installed fans, and sufficient GPU clearance. User reviews help validate build quality.
Many modern cases include USB-C, but confirm your motherboard has the required front-panel USB-C header.
Ensure the chassis supports at least 330–360mm GPU clearance to accommodate future high-end graphics cards.
Glass panels look premium but can crack under pressure. Steel panels are more durable and better at blocking noise.
Most mid-towers support 240mm or 360mm radiators, but verify exact radiator clearance before purchasing.
Typical setup: front/bottom intake, rear/top exhaust. Slight positive air pressure reduces dust buildup.
Start with at least two front intake fans and one rear exhaust, expanding as needed based on temperature.
Support glass with both hands, avoid impacts, and tighten screws lightly to prevent cracking.
Connect the case’s USB-C cable to your motherboard’s USB-C header. If absent, the port will not function.
Use dust filters, maintain positive pressure, and clean intake channels regularly.
Review user feedback for repeated mentions of difficult-to-close or uneven panels.
Some entry-level cases may have weaker hinges or clips—check reviews for recurring issues.
Cases without filters tend to accumulate more dust. Regular cleaning is recommended.
Thin panels or loose screws can cause vibration. Rubber grommets help minimize noise.
QC issues may include misaligned panels, missing screws, or paint inconsistencies. Check reviews before buying.
