PC case size guide

Your PC's case is more than just a protective enclosure; it's the gateway to unleashing your system's true potential. In today's computing world, PC cases come in various shapes, sizes, colors, and materials, offering functionalities to meet your specific needs in our PC case size guide.

Why the Right Case Matters

Choosing the right case is crucial because it directly impacts your components, such as motherboards, CPU coolers, power supplies, and drives, each with unique sizes and cooling requirements. Our comprehensive buyer's guide will empower you with the knowledge needed to make an informed decision when selecting a new PC case.

Motherboard Compatibility

The first and most crucial step is selecting a case that accommodates your motherboard. Manufacturers adhere to industry standards, ensuring compatibility. Here are the common standards for mid-tower and full-tower PCs:

• Mini-ITX: 170 x 170 mm
• Micro-ATX: 244 x 244 mm
• ATX: 305 x 244 mm
• E-ATX SSI-EEB: 305 x 330 mm

Remember, you can install a smaller motherboard in a larger case, providing benefits like enhanced cooling options and more drive bays. Your choice depends on your available space and specific requirements.

PSU Compatibility

Ensuring your case is compatible with your Power Supply Unit (PSU) is equally important. PSUs come in various standard sizes, including ATX, SFX, and TFX. High-wattage PSUs (1200W and above) might require a case with an extra-long PSU bay. Always check the specifications on the product page to be certain.

Cooling Capabilities

A well-designed case not only protects your components but also efficiently cools your system, keeping it quiet and functional. Cases are designed for air cooling, and some offer features for water-cooled setups.

Best Cases for Air Cooling

Even budget-friendly cases typically include fan mounts and fans. Entry-level PCs may only need a single exhaust fan, while high-end PCs require multiple fans for optimal cooling. Select a case with adequate fan mounts, preferably for 120 or 140mm fans. Leading manufacturers like Corsair provide information on the number of supported fans on their product pages.

Best Cases for Hydrocoolers

If you plan to use an all-in-one hydrocooler for your CPU or GPU, choose a case with the appropriate radiator mounts. Hydrocoolers come in three main size groups:

• 120/140mm (single fan)
• 240/280mm (two fans)
• 360/420mm (three fans)

Check the radiator size compatibility on the product page of the case.

Best Cases for Custom Water-Cooled PCs

Custom water-cooling requires space for radiators, pumps, reservoirs, and tubing. Some cases offer dedicated mounting points, while others require creative placement. Bigger cases are often better for custom water-cooling, providing more room for components and an easier building process.

Drive Bays

Consider your PC's drive requirements. Modern cases may omit external drive bays, so if you need a DVD or Blu-ray drive, ensure your case has a 5.25-inch external bay. For hard drives and SSDs, evaluate the number of internal 3.5-inch and 2.5-inch drive bays available.

Your PC case is the canvas for your ultimate computing masterpiece. At Hardware Hunt, we're here to guide you toward making the right choice, ensuring your PC runs seamlessly and looks great.
