Start with the case itself: check the front, both side panels, the back and the underside for a brand logo, model name or part-number sticker. If the tower is a prebuilt from a big manufacturer, use its service tag, serial number or product name on the maker’s support site. That route identifies the whole computer, though, and it may not name the case. If nothing is marked, you can narrow the search with clues, but you should confirm a match against the case maker’s own manual or product page before you treat it as fact.
Which route tells you the most?
These are four routes, not four competing tools. They differ in how directly they name the enclosure and in whether you have to open the case.

| Route | Identifies the case? | Need to open it? | How conclusive |
|---|---|---|---|
| Label, logo or stamping on the chassis | Usually yes, and most directly | Usually no | High if it shows a model or part number |
| OEM service-tag or product lookup | Identifies the computer; the case only if the maker lists it | No | High for the system, uncertain for the case |
| Markings inside the case | Sometimes | Yes | Moderate; may name a component instead |
| Visual comparison or community help | Possibly | No | Unverified until matched to an official source |
Step 1: Inspect the outside of the case
Check more than the front bezel. Look at:
- the front panel, near the power button or at the bottom edge, for a logo or model name;
- both side panels, including corners and edges;
- the rear, near the power supply and expansion slots, for a label;
- the underside and the top, if you can tip the tower safely.
Write down every marking exactly as printed: the manufacturer, any model or part number, and any serial or service identifier. A brand name alone is useful, because a maker’s support or product pages are often searchable by logo and by the shape of the front panel. If you post photos or labels online to ask for help, hide most of the serial number.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteStep 2: If it is a branded prebuilt, use the maker’s lookup
Large PC makers label the whole computer, and their support sites look it up by that label. Each one uses different wording, so follow the maker’s own guidance:
#1 Best Overall
- Comes with 4x pre-installed PWM-controlled 120mm ARGB fans, ensuring adaptable airflow and vibrant lighting with daisy-chain connectivity for easy setup.
- Integrated 26-LED ARGB strip offers full spectrum color control and synchronization with motherboard software, enhancing both visibility and aesthetics.
- Supports ATX, Micro-ATX, Mini-ITX, and back-connect ATX or Micro-ATX motherboards for cleaner routing and flexible builds
- Each side panel features a tool-less mounting mechanism for easy and fast access to internal components, streamlining your build process.
- Fits high-end hardware with support for GPUs up to 420mm, CPU coolers up to 178mm, and a top radiator up to 360mm
- Dell: Dell’s desktop guidance says the Service Tag or Express Service Code can be found on the desktop. You can also get it in Windows through SupportAssist and then enter it on Dell Support to identify the product.
- Lenovo: Lenovo Support describes the product name and serial number as being on a label on the rear of the chassis. Product and model details are also on the original box.
- Sony: Sony USA says the model name can be on a front label, and model, product and serial information can be on a rear barcode label or a combined label. Sony also warns that on some models the grey rear label’s “Model” entry is not the correct model name.
Model number, product code, serial number and service tag are different fields. Read the maker’s explanation of which one its lookup wants before you type anything in.
The lookup returns the computer’s original configuration or service documentation. It does not guarantee a standalone case model. If the case was swapped, or a system integrator used a separately branded chassis, the system record may not match what is in front of you.
Rank #2
- FRAME Modular Case System - The revolutionary FRAME system gives new meaning to the word customization. Want to upgrade the motherboard tray to billet aluminum? Want to swap out your front I/O panel for more USB ports? Now you can. A case that can change and grow with your needs (or just your mood). The options are nearly limitless
- 3x CORSAIR RS ARGB PWM Fans - High-performance fans pre-installed in the front of case. Support daisy-chainable 4-pin PWM connections and Zero RPM mode for near-silent operation at low loads. Each Fan has eight LEDs and easily controllable with your motherboard’s +5V ARGB connector
- CORSAIR InfiniRail Fan Mounting System - This steel multi-point mounting system offers unmatched flexibility in front and roof fan configuration. Simply slide the rail to mount fans up to 200mm (140mm in the roof) wherever you like, ensuring targeted airflow
- Clean Lines or Turbo Cooled - The internal side panel near the motherboard tray can be used as a cable cover for clean cable management, or you can remove it and mount fans to the side for increased cooling potential
- 3D Y-Pattern Airflow Panel - Optimized for high airflow and minimal restriction, the steel front panel is perforated in three dimensions with a Y-pattern that provides a low-obstruction path for cool air
Step 3: If nothing is labeled, check your records
Look at the original receipt, order confirmation, packaging and any manuals. If someone built the PC for you, ask the builder or the retailer which case they used. Boutique and system-builder machines often sit in cases from known case brands, and the builder can usually tell you which.
Step 4: Look inside, if you are comfortable doing so
This step is optional. Power the PC off and unplug it before removing a side panel. Some chassis carry a sticker or a stamped model or part number on the inner frame, the back of the motherboard tray or the inside of a panel. Treat anything you find as a lead, and check it against the case maker’s manual or product page.
Rank #3
- Ample Interior: Explore ample interior space for Micro-ATX or Mini-ITX motherboards, ensuring easy and future expansion
- Components Clearance: Accommodates CPU coolers with a max height of 159mm, GPU cards up to 360mm, and PSU up to 160mm in length.

- Modular I/O Panel: You have the flexibility to adjust its position at the front, top, or bottom on both sides
- Edge-To-Edge Panel: Show off your meticulous build through the transparent side panel with pride.
Step 5: Use visual clues, with care
If the case is unmarked or the PC has been modified, note its distinguishing features: the front-panel shape and mesh pattern, port layout, window style, number of drive bays and how the panels attach. Compare these with the product pages and manuals of candidate cases. Community forums can help narrow things down. A match from strangers is still a guess until an official page or manual confirms it, with the same dimensions, panel design and port arrangement.
What does not identify your case
A motherboard model does not tell you the case. ASRock says a board’s model can be found on the PCB, in its manual or box, in the BIOS, or through system-detection software. That helps with drivers and upgrades, and it may hint at what kind of system you have, but it describes the board only.
Rank #4

Likewise, a system serial number or service tag identifies the computer record, not necessarily the enclosure.

When you cannot get a definite answer
Generic, white-label and custom cases often have no online model record. It is common for people to ask this when planning an upgrade, as in an r/iBUYPOWER thread titled “How to find the PC case’s model number?”. Anecdotes like that show the question is common, but they don’t give a reliable method. Nothing guarantees that a serial number or a photo will return the exact model.
