Review: Perfect. - Best case for budget build for sure Big, and nice built in fans. Review: Good bang for the buck - Good bang for the buck. Comes with enough fans and is easy to build in. The velcro straps included do a good job at routing cables and keeping them bundled nicely. Only 1 or 2 more straps were needed for the power supply cables to keep them neatly tucked out of the way (velcro ones came with the power supply so I didn't use the included tie straps). I bought an extra 140mm fan to get 3 at the front and 1 exhaust. Using a dual tower CPU cooler not an AIO. Everything runs quietly. My only complaint is the piercing blue light used for the power button. It's damn bright in a dark room. Would've like for that switch's colour to be adjustable. I could just unplug the LED power cables but there's no real need to. ## Features - Fans Pre-Installed - E-ATX Mid Tower Case - High Airflow with Max Capacity ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C98TR925 | | Antenna Location | Business, Gaming, Personal | | Best Sellers Rank | #123 in Computer Cases | | Brand | Montech | | Case Type | Mid Tower | | Color | Base White | | Compatible Devices | E-ATX motherboards, long GPUs (up to 400mm), 360mm AIO coolers, vertical GPU mounting compatible | | Cooling Method | Air | | Customer Reviews | 4.8 out of 5 stars 62 Reviews | | Enclosure Material | Metal, Tempered Glass | | Fan Size | 140 Millimeters | | Global Trade Identification Number | 04710562744347 | | Hard Disk Form Factor | 3.5 Inches | | Internal Bays Quantity | 1 | | Item Dimensions D x W x H | 18.7"D x 9.1"W x 17.9"H | | Item Weight | 15.1 Pounds | | Light Color | white | | Manufacturer | Montech | | Material | Metal, Tempered Glass | | Mfr Part Number | AIR903BASEW | | Model Name | AIR 903 BASE | | Model Number | AIR903BASEW | | Motherboard Compatability | Extended ATX | | Number of Fans | 3 | | Other Special Features of the Product | Built-In Fan | | Power Supply Mounting Type | Mid Tower | | Recommended Uses For Product | Business, Gaming, Personal | | Supported Motherboard | Extended ATX | | Total Expansion Slots Quantity | 7 | | Total USB 2.0 Ports | 2 | | Total USB 3.0 Ports | 2 | | Total Usb Ports | 2 | | Warranty Description | 1 year | ## Product Details - **Brand:** Montech - **Motherboard Compatability:** Extended ATX - **Case Type:** Mid Tower - **Color:** Base White - **Material:** Tempered Glass, Metal - **Power Supply Mounting Type:** Mid Tower - **Cooling Method:** Air - **Fan Size:** 140 Millimeters - **Number of Expansion Slots:** 7 - **Number of USB 2 Ports:** 2 ## Images ![Montech AIR 903 Series, E-ATX Mid Tower Case, High Airflow, Fans Pre-Installed Gaming case (Air 903 Base White) - Image 1](https://m.media-amazon.com/images/I/81qGA9UC1rL.jpg) ![Montech AIR 903 Series, E-ATX Mid Tower Case, High Airflow, Fans Pre-Installed Gaming case (Air 903 Base White) - Image 2](https://m.media-amazon.com/images/I/81g2xoJCGIL.jpg) ![Montech AIR 903 Series, E-ATX Mid Tower Case, High Airflow, Fans Pre-Installed Gaming case (Air 903 Base White) - Image 3](https://m.media-amazon.com/images/I/71eoDl7wpmL.jpg) ![Montech AIR 903 Series, E-ATX Mid Tower Case, High Airflow, Fans Pre-Installed Gaming case (Air 903 Base White) - Image 4](https://m.media-amazon.com/images/I/614fnoyI6TL.jpg) ![Montech AIR 903 Series, E-ATX Mid Tower Case, High Airflow, Fans Pre-Installed Gaming case (Air 903 Base White) - Image 5](https://m.media-amazon.com/images/I/71+8gfHsX5L.jpg) ## Available Options This product comes in different **Color, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect. *by B***V on December 30, 2025* Best case for budget build for sure Big, and nice built in fans. ### ⭐⭐⭐⭐⭐ Good bang for the buck *by C***S on August 31, 2025* Good bang for the buck.

I decided I needed a smaller computer case this time. Went with a Mid-tower and wow! It's it's bigger than I thought. Certainly room to expand if I need another hard drive or 2. Great cable management with it being out of sight. Several shrouded slots to run the cords through behind the motherboard. The screen on the top is held on with a thin, weak magnetic strip all the way around it. Great for removing and cleaning. Strong possibility I will use this same case on my son's upcoming computer build. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/536629919-montech-air-903-series-e-atx-mid-tower-case-high](https://www.desertcart.com.sa/products/536629919-montech-air-903-series-e-atx-mid-tower-case-high) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-05-31*
