In the battle between Mid Tower vs Full Tower, which case form factor comes out on top?

Truthfully, the answer depends on you and your needs, whether that’s for running a server, rendering video, or even just playing some video games.

Below, we’re going to go over everything you need to know before picking between these two form factors. Let’s get into it!

Understanding Case Form Factors

Full Tower Cases

First, let’s talk about Full Towers.

A Full Tower PC case will usually be more than 20 inches (50cm) tall, and possess room for 7+ 3.5-inch drive bays, lots of cooling fans, and enough expansion slots for Extended ATX.

Depending on what specific Full Tower case you pick, it may be optimized more for expansion or cooling.

Some Full Tower cases even offer room for an entire secondary PC inside the same chassis, but we’ll discuss that point in a little more detail later.

Where other cases have to make lots of compromises around size in order to meet their goals, most Full Tower cases are focused on raw performance and expansion rather than slimming down their footprint.

Mid Tower vs Full Tower Size Comparison

This is great for those with such priorities, but it does make for a larger, heavier, and more expensive chassis than the alternatives.

Mid Tower Cases

A Mid Tower PC case will usually be under 20 inches tall (< 50cm), and closer to 17 inches (43cm).

Generally, this means room for 4+ 3.5-inch drive bays, at least 3 intake fans, and expansion slots to match a standard ATX motherboard.

While Mid Towers are reasonably smaller than Full Towers, they are still pretty big when compared to smaller form factors and today’s ever-shrinking consumer PCs.

A rare few are also capable of dual-PC builds but expect to go all-out on cooling fans or liquid cooling if you do that in a Mid Tower case.

While Mid Tower cases show some compromises compared to Full Towers, these compromises should mean almost nothing to the majority of consumers.

If you aren’t using all of your expansion slots or more than one hard drive, even Mid Tower might be slightly exaggerated for your needs.

What a Mid Tower does best, however, is keep the spirit of PC upgradability alive. even if you aren’t using multi-drive or multi-card setups today, a Mid Tower gives you the ability to move up should you ever want or need to change your mind. Additionally, Mid Tower cases do not have to deal with as many limitations as smaller form factors when it comes to keeping the hardware cool.

If you want great airflow and good expansion capabilities for cheaper than Full Tower, Mid Tower is a great choice. We’ll break down more of the specifics below.

Why A Mid Tower Case Is Best

Great Drive Storage

Mid Towers usually offer 3-4 3.5-inch drive bays, as well as 3-4 2.5-inch bays to match.

This is more than enough for having multiple HDDs, multiple SSDs, or even both in a single PC.

Storage Space in Mid Towers PC Cases

For consumers and gamers, this should be more than enough room for the ideal internal storage setup.

For the highest-end storage setups (especially for servers), though, this still might not be enough.

Majority of Cooling Options Work Well

Want a fully air-cooled PC? A Mid Tower case will be one of your leading options, especially if you want to maximize airflow.

While Full Tower cases are also great in this regard, a Mid Tower cases’ smaller footprint makes it just a little bit easier to push air through them. It’s pretty easy to get a good positive pressure airflow setup inside a Mid Tower case, especially when compared to a smaller chassis.

Liquid cooling setups work well here too, whether you’re using an AIO or a custom loop setup. While you can technically even get custom water loops running in a Mini ITX build, it’s a headache.

Mid Tower cases have much more room to work within comparison and are also compatible with larger AIOs/radiators than a smaller chassis would be.

2+ GPUs or Expansion Cards

Especially with modern GPUs, the majority of users aren’t using multi-GPU setups.

Even gamers, who used to love that kind of thing, have largely been turned off of multi-GPU setups by the dwindling number of games that actually support using more than one GPU at a time.

For professionals, however, even just one more GPU can make a significant difference in render times.

Most people would be better served by a single, powerful GPU that meets their needs, though- especially in today’s era of chip shortages.

Size & Weight Reined In Comparison To Full Tower

Last but not least, the most obvious point: Mid Tower cases are smaller and lighter than Full Tower cases.

If you’re going to need to move your PC with any kind of regularity, it’ll be considerably easier to do that with a Mid Tower or smaller case than with a hulking Full Tower chassis.

Additionally, the cost of raw materials tends to drive up the cost of a Full Tower compared to a Mid Tower- you can save some money by going for a Mid Tower instead.

Why A Full Tower Is Best

The Most Drive Storage

If you’re sure you want a higher-end multi-drive setup, then a Full Tower case should catch your eye. Especially if you’re trying to build a server, having 5 or more 3.5-inch bays at your disposal will come in handy.

Benefits and Storage Space in a Full Tower PC Case

5.25 bays for disc drives and card readers have become incredibly rare on the PC market, but if you’re looking for those you’re most likely to find them in a Full Tower as well.

If you want scalable, RAIDable, and stackable storage for the foreseeable future, a Full Tower case is a great option.

Best For High-End Cooling

If you want to have a high-end cooling setup with a large radiator or two (AIO or custom loop), then a Full Tower case is what you should be looking at. Especially if you want to do something extreme, like custom loop cool your CPU and more than one GPU, a Full Tower case presents itself as the ideal option.

Regular air cooling can still be extremely good in a Full Tower case, but you’ll also need to buy more case fans than with Mid Tower to keep air flowing throughout the whole case and not build up hot pockets in areas.

3+ GPUs or Expansion Cards

Multi-GPU setups may not be as popular as they once were, but for the discerning enthusiast or professional who demands them, a Full Tower case is the best – and often, the only – choice.

GPU Compatibility in Full Tower PC Cases

At this point, we’d just like to make sure that you know when to choose a blower-style graphics card over an open-air graphics card since blowers are generally much better in multi-GPU setups than their counterparts.

Dual-PC Builds Possible With Some Full Towers

While a few Mid Towers out there have dual PC build configurations, most cases that offer this feature are Full Tower or larger.

Now, even some of the pros among you might be asking: why would I want to put 2 PCs into a single chassis? Similar to the multi-GPU point, it really does depend on what kind of tasks you’re doing and how scalable they are across multiple processors.

Many pro applications support putting 2 or more PCs on a network onto the same task simultaneously, for instance.

Meanwhile, content creators (especially gamers who live-stream) can make great use of a chassis like this.

Your typical dual PC case will offer your standard ATX or Extended ATX PC build but include the option to mount an additional Mini ITX motherboard somewhere else inside the case, usually at the top or bottom.

In these cases, you can spend less on the ITX PC and dedicate it fully to streaming or rendering your video without interrupting your gaming or editing workload on your main PC.

If you opt for something like this, though, you’ll definitely want to consider amping up your cooling as much as possible. The secondary PC may not generate the same level of heat, but it will still be generating extra heat that your case needs to get rid of, somehow.


Are Mid Tower and Full Tower cases required for the best performance?

Not necessarily.

While a Mid Tower case is roughly the best for raw airflow and you can maximize liquid cooling’s potential with a Full Tower case, you can still do pretty well with smaller form factors.

What’s important if you still want great performance in a small form factor is knowing how to optimize around it.

For instance, did you know that blower-style GPUs are the best for SFF PC builds? This is because standard open-air designs exhaust heat into the rest of the case, and generally are more reliant on strong airflow than blower-style cards are.

Optimizing cooling in an SFF case

Custom loops and AIOs tend to perform well in SFF builds too, but they are still limited by fewer fan slots for mounting radiators.

It’s also generally more difficult to build inside of an SFF case, especially when you’re going as far as doing a custom loop.

Are Mid-Towers good for gaming?


If your only concern is gaming, then you most likely don’t need a Full Tower case. But if you want a multi-slot GPU with an open-air cooler, a Mid Tower case with a decked-out fan configuration is probably going to be your best bet.

Liquid cooling your components for overclocking will work great in a Mid Tower case, too!

When should I consider a Micro ATX or Mini ITX case instead of a Full or Mid Tower?

Finally, let’s just be real: when should you downsize from the main form factors talked about in this article?

Well, if you don’t need a lot of drives or GPUs, chances are a Micro ATX case should serve you fairly well.

If you want to maximize your space-saving and you’re confident that you can build and maintain it, you can even go for a Mini ITX or other SFF PC build, but don’t expect everything to work well or even fit into your case at that point.

If you still want the benefits of a Mid Tower case but want something with a smaller footprint, check out our article on the best small ATX cases.

These aren’t quite SFF but they are generally much more workable than your standard Mid Tower or Full Tower designs, and you won’t sacrifice nearly as much using one of those as you would with Micro ATX or Mini ITX.

      Hey Vijay,
      I like all of your suggestions. The PSU picks and case picks are very similar. I’d probably go with the Corsair PSU and the meshify 2, as both of these are products that have been on the market for quite some time and are known to be reliable.
