PC Case Guide | Which Form Factor Is Best For You?


The most important component of a PC build is the case. Without it, you wouldn’t have a place to build in.

We are going the different types to determine the best case type for you.

Let’s go from smallest to biggest form factor.

Mini-ITX Case

Starting off with the smallest form factor. Mini-ITX cases have a lot of positives while also bringing some negatives.

So, the obvious downside is compatibility. While this has improved lately, mini-ITX compatible hardware is, in some cases, not available or more expensive. For example motherboards.

There is also less future proofing with most mini-ITX motherboards only having 2 RAM slots and 1 PCI-E slot.

The building process is also a slight bit more difficult but the newer cases are beginner friendly.

Luckily enough there are also a fair share of positives. Beginning with the satisfaction of completing a mini-ITX build. Since the process is more difficult most people also see it as an accomplishment.

Along with looking very clean and minimal small cases also fit in more areas. This is especially good for gamers who take their PC with them.

Micro-ATX Case

Coming to the case that is in-between the mini-ITX and ATX case. The micro-ATX case is smaller than a normal TAX case but doesn’t compromise as much as the mini-ITX.

The negatives are basically non existent. The only real negative is that it doesnt give you the satisfaction or minimalist look that the mini-ITX case gives you.

This case has almost all of the positive sides of the ATX and mini-ITX case. A lot of gamers that have little space but don’t want a mini-ITX case go for the micro-ATX case.

ATX Case

This is the most used case on the market. This case has the normal dimensions and can fit almost any hardware out there.

The positive side of this case is that it supports a lot of hardware. Also building in it will be very easy since you have enough space for the hardware and cable management.

Micro-ATX Case

When choosing an ATX case you will have enough to choose from.

As for the negatives, if you plan to put this case on your desk it might seem very big. That is pretty much the only negative.

Some might argue that these don’t look minimal or clean enough. If you are a fan of minimalism go check our minimalist setup guide.


Coming to the last and biggest form factor. The EATX and XL-ATX cases are absolutely huge. You can’t put them on your desk without looking obnoxious.

Most ETX and XL-ATX cases have a dual chamber layout. Meaning that you can have 2 systems on either side.

These cases are made for 2 PCs 1 case or insane custom water cooling loops. You can fit anything you would ever want in these cases. Multiple GPUs, no problem.


The biggest negative is the size and price. Like previously mentioned these cases are huge. The EATX and XL-ATX cases will easily run you a few hundred euros.

So take into account that these are not beginner cases and you will need a lot of hardware to fill that thing.

A lot of streamers go for these cases. They then put their gaming rig on one side and streaming/editing rig on the other.


If you still can’t decide which form factor is best for you, take a look below.

Mini-ITX = Minimalists, People with little space

Micro-ATX = ATX too big mini-ITX to small

ATX = First-time builders, Most variety

EATX / XL-ATX = Custom water cooling loops, dual systems
