Now let’s compare these two cases in more detail!


The most apparent difference between Full Tower and Mid Tower cases is their size. 

As mentioned earlier, Full Tower cases are larger and typically measure around 20″ to 27″ long and 20″ to 27″ high. On the other hand, Mid Tower cases are smaller and usually measure around 18 inches tall, 18 inches long, and 8 inches wide.

The larger size of Full Tower cases means that they offer more space for components and customizations. However, Mid Tower cases are more compact and can fit comfortably on a desk or under a desk.


Motherboard Support

Motherboard support is another critical factor when it comes to choosing between Full Tower and Mid Tower cases. 

Full Tower cases support Extended ATX (EATX) motherboards, which are larger and offer more PCIe slots for expansion. Mid Tower cases, on the other hand, usually support standard ATX motherboards, microATX, and mini-ITX, which are smaller and have fewer PCIe slots.

If you’re building a PC with an E-ATX board or an EE-ATX motherboard, you’ll need a full tower case. However, if you only want to fit a standard ATX or mini-ITX motherboard, you can go with a mid-tower case.

Drive Bays

If you do video editing or play games, you may quickly run out of storage space, especially if you use SSDs. Nowadays, games take up a great deal of space. For example, The Elder Scrolls V: Skyrim was under 10 GB at launch but grew to 12 GB after DLC. In addition, Grand Theft Auto 5 and Call of Duty Black Ops Cold War take up 72 GB and 175 GB of storage space, respectively.


Fortunately, standard HDDs are now relatively cheap, but you still need to install them in the drive bay.

If you’re a casual gamer or don’t require much storage or additional features like a Blu-ray drive, a Mid Tower PC Case will be enough. But for larger storage needs, Full Tower Cases are better. You need a Full Tower PC case for video editing, photo editing, storing RAW files from your DSLR, or dealing with huge AutoCAD drawings or 3D models.

PC cases typically have SSD side mounts that free up 3.5″ drive bays. Mid Tower PC Cases have 1 to 3 SSD drive slots, whereas full towers have 2 to 6.

If you choose a Mid Tower case, you can always buy external hard drives, which are plug-and-play. It’s a good idea to have a backup on an external hard drive in an emergency. USB 3.0 external hard drives are fast, reliable, and affordable at an all-time low price. 


PCIe Expansion

A major advantage of Full Towers over Mid Towers is the PCIe slots. Even though an extra slot may not seem like much, it can make a big difference if you plan to install multiple GPUs. This is especially crucial if you work with 3D models or engage in professional 3D rendering because these tasks require several graphics cards to handle the workload effectively.

In addition to spacing out graphics cards for better cooling, more PCIe slots help you optimize airflow within the case. You can prevent overheating and prevent damage to your expensive hardware by increasing the distance between the cards.

In simple terms, if you are a professional in the 3D industry, a Full Tower case may be your best bet. This ensures that your setup runs efficiently and effectively.

Air And Liquid Cooling

To ensure optimal performance, it is important to maintain a cool temperature within your computer. But this is not always the case, as many computer components generate heat during operation. 


Luckily, you can easily improve the cooling system by adding extra fans to your chassis. The more air circulates through the case, the more heat dissipates, and the components operate at cooler temperatures.

Effective airflow is crucial for maximizing your computer’s performance. The Full Tower PC Case is naturally larger, offering more space for additional fan mounts. But the Mid Tower Cases are just as capable of maintaining proper airflow and keeping your components cool.

Size also plays a significant role in cooling efficiency. A larger case provides more space for air to pass through, ensuring optimal cooling performance. Therefore, Full Tower Cases are better at maintaining a healthy airflow because fewer obstructions could hinder air circulation. The components are also spaced further apart, which aids in maintaining a healthy temperature.

Additionally, this provides ample room for the CPU cooler and GPU fans to work effectively. Larger motherboards also provide more space between the heat sinks, graphic cards, and CPU coolers, reducing disruptions in the airflow.


Liquid Cooling – If you plan to incorporate liquid cooling in your PC, a larger case will make installation easier. Liquid cooling systems come in two configurations: closed-loop and open-loop. Open-loop systems require regular maintenance, which is easier to perform on a Full Tower Case. The larger size also provides more options for bigger radiators, making it easier to mount them.

As a result, both Full Tower and Mid Tower Cases are excellent options for keeping your computer components cool. But if you plan to incorporate liquid cooling or want more space for fans, a Full Tower Case would be a better choice.

Noise Levels

As far as noise levels go, Full Tower PC Cases are generally quieter than Mid Tower cases. This is because they can accommodate multiple fans to maintain a cooler temperature. With a proper push-and-pull fan arrangement, your fans won’t have to work too hard, resulting in a quieter overall experience. 

Some Mid Tower Cases also offer noise-dampening features, making them a suitable option for those who want to game or work quietly without disturbing others. The Fractal Design Define S is an excellent example of a Mid Tower case with noise-reducing features. It can help maintain a peaceful environment even during intense gaming sessions.



Price is always a consideration when it comes to building a PC. Full Tower cases are typically more expensive than Mid Tower cases due to their larger size and more extensive feature set. If you’re on a tight budget, a Mid Tower case is a great option.
