The future of computer cases is open-air, with more and more companies putting in liquid cooling solutions.

Before choosing an open-air PC case over a standard chassis, consider a few things. These may be rather pricey, and they’re essentially intended for water-cooling experts. However, there are specific common concerns for all builders; let’s look at them.

Dimensions of the Motherboard


The most prevalent form factors for motherboards are ATX, Micro-ATX, and Mini-ITX, with ATX being the most prominent and Mini-ITX being the smallest.

Smaller motherboards, by definition, have less space for your components, fewer features, and fewer fan headers. Trim may be ideal for you, but the members and case size should determine this. In most circumstances, if you’re building a high-end PC, an ATX motherboard is the way to go.

Of course, it’s not only motherboards that come in different sizes; GPUs, power supplies, and coolers also come in different sizes, so double-check.

Form Factor of an Open-Air Case


The form factor of a computer case is often labeled to give you a quick indication of what motherboard compatibility it will support. If not, don’t panic; any product’s specifications will specify precisely what will fit inside!

As you can see, the size of this list of the best open-air cases varies a lot, with some in the mid-tower category and others in the Mini-ITX category.

The following are the three most common PC case sizes (but there are others):

  • Full-tower PC cases are the most powerful and can accommodate E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards. Their enormous size is primarily for additional components than for really large motherboards.
  • Mid-tower PC cases are the most common and, with a few exceptions, can operate with motherboards as big as ATX.
  • Micro-ATX and Mini-ITX boards can still be used in Mini-ITX PC cases, sacrificing the larger ATX boards.

As a side note, when utilizing tiny form factor motherboards with significant form factor cases, keep in mind that the front panel wires may struggle to reach, resulting in poor cable management.


As you may expect, an open-air container provides less protection for your components. This is because dust follows air passage and passes through your intake fan in a standard case (unless you have significant gaps in your case and negative pressure).

Because your components are all pretty cooled, there is no need for air intake in open-air enclosures. While this is excellent news for your temperatures, it will need additional caution and attention in terms of dust. Regular cleaning of your open-air PC is essential since dust will quickly gather in this sort of casing.

Dust accumulation is a significant concern to components, but there are also more risks to consider if your case is open. Be cautious of pets near open-air systems (for obvious reasons), and be especially careful with liquids, as there will be little to prevent spills.

Frequently Asked Questions

Are open-air PC cases worth it?

A: If you want the best sound, I recommend getting a closed case.

Are open PC cases any good?

A: Most open cases are horrible because the outside of the issue is not generally well-ventilated. Available issues can also be overly loud and create a lot of noise, so they might disturb your neighbors if you use them constantly.

Can you leave the PC case open?

A: Yes, PC cases can be left open.
