Best Horizontal PC Cases Reviews and Guide

It is undeniable that vertical cases dominate the industry. Tower-style cases will predominate on any “best of” list for PC cases. Towers are fine, but the best horizontal cases can accomplish some tasks more effectively. They are perfect for small HTPC projects and living room PCs, for example.

Horizontal PC cases have a unique appearance as well, and they can just provide the inspiration you need for your upcoming build.

When constructing a custom computer, you are free to choose the case you like and the components that work with it. As a result, there is a wide range of PC cases. PC cases come in a variety of shapes and form factors. But because of installation problems and space limitations, consumers frequently choose smaller cases.

A horizontal PC case can be a good choice for them. These cases are suitable for high-capacity PC components in a small form factor while having a bigger footprint and a height of fewer than 10 inches. Before you purchase a horizontal PC case, you should absolutely keep in mind the following aspects.

Motherboard Compatibility:

Only a PC case that is compatible with the motherboard of your choice is appropriate for your setup. Even motherboard form factors, such as ITX, ATX, micro ATX, and tiny ITX, are very diverse. Make sure your motherboard is listed as compatible with the case because only a select selection of these motherboard form factors are compatible with the cases.

Size:

The size of the case is one of the primary arguments in favor of choosing a horizontal PC case over a traditional vertical design. Make sure the horizontal PC case’s size is appropriate for your desk area before making a purchase. As you may already be aware, horizontal PC cases take up substantially more space in terms of length and width than they do in terms of height.

Cooler and GPU Compatibility:

Along with the motherboard, you need also make sure the case is compatible with the CPU cooler and graphics card. Due to the size of the latest generation of graphics cards, it is much more crucial now. You may have been aware that high-capacity air CPU coolers are somewhat large in size. Additionally, because the horizontal PC case’s height is already insufficient, it has a smaller range of compatibility with large CPU coolers.

Even if the elements listed above are among the most important characteristics of a PC case, you still need to learn a lot more before making a decision. Thankfully, you won’t have to go through hundreds of possibilities because we have already narrowed down the top horizontal PC cases right here. Keep reading our buying guide for the top horizontal PC cases, where we’ll tell you even more about the crucial characteristics of a PC case.

Buying Guide For The Best Horizontal PC Case

Custom PC builds are much more common than ready-made systems these days. You can select the components that are most important to you and the PC casing that appeals to you the most when you build a personalized computer. There are numerous brands on the market that create PC cases expressly for this purpose in a range of form factors.

Today, we discussed the top horizontal PC cases on our list and provided in-depth details for each of our selections. To provide you with a thorough understanding of what you will receive when you purchase the case, we have also included a list of the top features with each of our recommendations. Check out our shopping guide for the best horizontal PC cases if you still want to learn more about horizontal PC cases.

Motherboard Compatibility

No matter what kind of PC case you purchase, you should always verify that it is compatible with your motherboard to receive the greatest results. If you’ve been wanting to construct a custom PC for a while, you may have decided on the motherboard, CPU, GPU, RAM, and other parts that you want to put in it. To build a completely functional custom PC, your case must be perfectly compatible with each of these parts. We advise you to focus on the motherboard area in the compatibility section.

It is typically addressed as soon as possible so that you may quickly determine whether your case is compatible. Simply confirm that your motherboard has the same form factor as your case type. In general, there are numerous motherboard options available, including ATX, micro ATX, mini ITX, and many others.

CPU Cooler and GPU Support

The CPU coolers and GPUs are the 2 most significant components of your PC, aside from the motherboard, which frequently causes compatibility problems. Make sure your horizontal PC case can accommodate the CPU cooler of your choice before you finalize it. Depending on the brand and quality of the air cooler you choose to purchase, the air CPU coolers might be rather considerable in size. Even in the case of an AIO or liquid cooler, your case needs to support the same-sized radiator as the one that came with your AIO.

When it comes to the GPU, the main problem in this situation is the GPU length. You will need to purchase a whole separate card if the GPU cannot be fitted in a case, which is not the best situation. And given the state of the market, it’s possible that you won’t have access to another option for a while. Simply measure the length of the GPU you intend to install in your system and confirm that it is compatible with the casing to avoid such issues. Most case makers list the supported GPU length in mm, which should be greater than the length of your GPU.

PSU Support

Since the system cannot be turned on without a specific power supply unit, the PSU is also a significant part of your system. The overall power requirement is relatively high for the most recent generations of CPUs and GPUs. Therefore, if you want to build a high-capacity gaming computer with the most recent version of CPU and GPU, you will need a very hefty PSU. But for that, your casing must be able to easily accommodate such a device.

To do that, you can first determine whether the horizontal PC case is compatible with the PSU of your choice. The compatibility criteria for PSUs in PC cases are comparable to that of a motherboard. PSUs are made in common form factors like ATX or SFX, which your computer case must support. While the majority of horizontal PC cases work with ATX power supplies, a few models may only work with SFX power supplies, which are noticeably smaller in size.

Cable management

They provide cutouts in the motherboard tray so that your case will seem visually pleasing. The cable may be moved out of the backside in a smooth and simple manner thanks to this. Budget computer casings include many holes, while mid-range cases also come with rubber grommets for a neater appearance. There are also tie-off points and unusual chambers to conceal the wiring.

PCIe Expansion Slots

Finally, we advise you to carefully examine the available PCIe slots on your chassis. You could be unsure of whether to examine the motherboard’s PCIe slots or the casing. You should thus verify that PCIe slots are available on both ends in order to achieve optimal results. Dedicated PCIe installation ports in the enclosure enable the installation of PCIe-powered components while PCIe connectivity is provided by the motherboard.

In addition to the graphics card, you might also require network cards, audio cards, extra USB hubs, tuner cards, and other PCIe components in the future. Your case needs to have additional PCIe expansion slots for that. To acquire a PC design that is future-proof, even if your case is small in size, you should choose a solution that includes at least two to three PCIe expansion slots overall.

Frequently Asked Questions

Is it possible to use a standard PC case in horizontal orientation?

Well, the majority of common instances can be employed horizontally with no issues. However, the sole requirement is that the PC parts must be assembled so that it resembles a horizontal PC case in shape. The bulk of PC components don’t have any moving parts, thus the orientation shouldn’t be a problem. Having said that, if you want to position the PC case in a horizontal posture, we still advise obtaining a good horizontal PC case to be safe.

Is it possible to install case fans on a horizontal PC case?

Cooling fan slots are specifically designated while designing PC enclosures. You will be able to install the cooling fans of your choice even if you choose a horizontal PC case. To achieve the best possible airflow inside your case, however, be careful to put the fans in the proper direction. The majority of the time, fans made for normal PC cases may be easily put into a horizontal case.

Do I need a PSU shroud inside the PC case?

The performance of your system or the PSU powering your PC is unaffected by the PSU shroud. However, it unquestionably adds to the aesthetics and aids in producing a clean PC build, which is favored by many users. Most of the bulky, unsightly cables coming out of the PSU can be readily hidden if your case has a PSU shroud. You will be able to further personalize your PC with specialized lighting or a figure of your choosing while managing the cords within your case more simpler.

What is ATX Mid-tower?

Between the full tower and mini-tower sizes, the ATX mid-tower category includes tower-type PC chassis. ATX-mid-tower PC cases are typically small, and light, and provide plenty of room for expansion cards in addition to having the necessary cooling system components. This size is typically the most popular since it provides complete capabilities while maintaining the system’s size in the compact range.

What are horizontal computer cases called?

Since the advent of personal computers, the horizontal chassis has historically been the default position. Given that the chassis is placed on top of your desk, it is commonly referred to as a desktop computer. The phrase “Desktop PC” is now frequently used to refer to both horizontal and tower-type enclosures. Tower designs are favored over horizontal desktops due to additional room inside the chassis, which has become necessary with the introduction of larger expansion cards and sophisticated cooling systems.

Are horizontal PC cases good?

The horizontal PC chassis is intended to add beauty to your space. Additionally, a horizontal case saves a lot of space in terms of height, as the name suggests. But the needed space is managed by increasing the length and width in order to accommodate whatever you want within the case. However, it’s important to examine the compatibility of CPU/GPU cooling as well as motherboards while shopping for a horizontal PC.

What is an inverted PC case?

The best way to explain inverted PC cases is as chassis with an upside-down configuration. The CPU and GPU are installed on top of the motherboard in the conventional layout, but in an inverted casing, the components face downward instead of upward as in the conventional layout. Depending on the chassis design, the PSU might be placed top or bottom depending on the arrangement.

Conclusion

When it comes to PC cases, the market offers a wide variety of choices. First off, there are groups of PC cases based on the form factor and size of the motherboards that they are compatible with. After that, consumers can find a number of possibilities before choosing a PC case for their custom PC build thanks to the various options that are then offered for each form factor.
