Start with the parts you plan to use, then match the case. Case size is tied to your motherboard and space needs:

• Motherboard fit: Choose a case that supports your board (Mini‑ITX, Micro‑ATX, ATX, or E‑ATX). Mid‑towers commonly fit ATX; mini cases fit smaller boards.
• Component space: Check maximum GPU length, CPU cooler height, and PSU length. Some cases list support for long GPUs and tall air coolers.
• Cooling plans: Look for radiator support (240/360mm) and fan mounts if you want high airflow.
• Front I/O and drives: If you need Type‑C or extra storage, confirm the specs.

You can use site filters and the product spec table to narrow choices. Designs and dimensions vary by model.

Clearances are listed on each product page and can vary by design. A quick check helps avoid surprises:

• GPU: Look for “Max GPU length/height/thickness.” Measure your card end‑to‑end and account for power plugs and cables.
• CPU cooler: For air coolers, find “Max CPU cooler height.” For liquid coolers, review radiator locations (front/top/side) and lengths (240/280/360mm) and consider fan thickness.
• Top/front space: Tall RAM or motherboard shrouds may affect top radiator clearance.
• PSU and cables: Longer power supplies can reduce front radiator or drive space.

If you’re unsure, compare the listed maximums with your component dimensions. Allow a little extra room for easier building and better airflow.

Fan needs depend on your parts and case design, but a balanced layout is a helpful starting point:

• Baseline: Two front intakes plus one rear exhaust can offer solid airflow for many builds.
• Size matters: 140mm fans can move similar air at lower RPM than 120mm, which may help with noise.
• Pressure: Slight positive pressure (more intake than exhaust) can help reduce dust through unfiltered gaps.
• Front panel: Mesh fronts typically breathe easier than solid glass fronts at the same fan speeds.

Many cases include pre‑installed fans, and some support extensive fan/radiator setups. Placing fans thoughtfully can be as effective as adding more, but results may vary with your components and room temperature.

A little planning goes a long way toward a clean look, especially with tempered glass sides:

• Plan routes first: Use the case’s cable channels, grommets, and tie‑downs. Pre‑measure paths for 24‑pin, CPU EPS, and GPU power.
• Use fewer, flatter cables: Modular power supplies and slim SATA cables can reduce clutter.
• Secure gently: Velcro straps or zip ties help bundle runs without crushing them. Avoid sharp bends near GPU power connectors.
• Leverage space: Dual‑chamber layouts and PSU shrouds can hide excess cable length.
• Final checks: Close panels carefully and don’t overtighten glass screws.

Always power down and unplug before working inside the case. Neat cabling can improve both airflow and aesthetics.

Regular, gentle cleaning can help your PC case look great and breathe better:

• Power off and unplug: Safety first before opening panels.
• Dust filters: Remove magnetic or slotted filters. Tap out dust, then rinse with lukewarm water if needed. Let them dry completely before reinstalling.
• Inside the case: Use short bursts of compressed air; hold fan blades to prevent overspinning. Avoid spraying liquids into the chassis.
• Tempered glass: Wipe with a microfiber cloth. If needed, use a small amount of isopropyl alcohol or screen cleaner—apply to the cloth, not directly to glass.
• Avoid harsh cleaners: Skip ammonia‑based products and paper towels that may scratch.

Cleaning frequency depends on your environment and fan setup.
