To figure out what PC case you have, start by physically inspecting the case itself, because the model number is almost always printed on a label or stamped directly into the metal or plastic. The fastest way to answer "what PC case do I have" is to look at the exterior surfaces for a manufacturer's logo, a model name, or a serial number, which are typically found in the locations described below.
Check the bottom and back of your PC case first
The single most reliable place to find your case's identity is on the bottom panel or the rear I/O area. Manufacturers place a permanent label or engraving here because it's out of sight but still accessible without removing any parts. For example, Fractal Design cases have the serial number located on the bottom of the case or on the outside of the retail box, and it will look like "1234RTL0123456789" or "1234FD01234567890". Look for a small, often white or silver sticker with barcodes and text, or a laser-etched code near the power supply mounting area. If the case sits on your desk, carefully tilt it or lay it on its side to read the underside. The rear panel, near the expansion slot covers or the motherboard I/O shield cutout, may also have a printed model number, especially on older or budget-oriented cases.
Look behind the front and side panels
If the bottom and back yield nothing, the next most likely spots are hidden behind the front and side panels. Many cases hide their branding and model information behind a snap-off front bezel or a tool-less side panel for a cleaner aesthetic. To check, remove the left side panel (usually secured by two thumb screws at the rear) by sliding it toward the back of the case. Then, inspect the inside surface of that panel, as well as the metal frame near the drive bays or the front fan mounts. The front bezel, which often clips into place, can be pulled gently from the bottom corners to reveal a label on its inner surface or on the chassis behind it. Always unplug the power cable and ground yourself before touching any internal components, but you don't need to remove any parts that aren't designed to come off. This method is particularly useful because it lets you see the model printed on a sticker that was placed during manufacturing, which is rarely visible from the outside.
Find the original box, manual, or receipt
When the case has no external markings, your purchase history becomes the definitive source. If you kept the original box, the model number is printed on the end flap or the main face in large type, along with the manufacturer's name and often a barcode. The user manual, if you have it, will list the model on the cover page or the first few pages. A digital receipt from an online retailer or a physical invoice from a store will include the exact product name, which you can cross-reference with the manufacturer's website. This approach is also useful if the label has worn off or been scratched away, because the box and manual are stored separately and won't have suffered the same wear. If you don't have the physical items, check your email for an order confirmation or your account history on the retailer's website, as these records almost always contain the full product title.
Contact the manufacturer as a last resort
If you've exhausted all physical inspection methods and have no packaging or receipt, the manufacturer's support team can identify the case from photographs and a detailed description. Before you reach out, take clear, well-lit photos of the case's front, back, side, and any labels you did find, even if they're partial. Also note the case's dimensions, the number of drive bays, and the position of the front I/O ports (USB, audio, power button). Prepare this information and send it through the manufacturer's official contact form or support email, which you can find on their website. This method is slower than the others, as support teams handle many requests, but they have access to product databases and can often match your photos to a specific model. If you're also wondering how to tell PSU without opening the case, note that the same label that identifies the case often lists the power supply's wattage and model, so check that sticker while you're looking for the case name.
