Best Horizontal PC Case Reviews

If you are building a custom PC, you have the freedom of choosing the case that you want and then you can select the parts compatible with it. Thus, there is a lot of variety when it comes to PC cases. You will find PC cases in different form factors and designs. But in a lot of cases, users prefer getting a smaller case due to installation issues and space restrictions.

For those, a horizontal PC case might be a decent option. While these cases have a larger footprint, their height lies within 10 inches, making them viable for high-capacity PC components within a compact form factor. Here are some essential features of a horizontal PC case which you should definitely keep in mind before you buy one.

  • Motherboard Compatibility: A PC case is only suitable for your build if it is compatible with the motherboard of your choice. There is a lot of variety even in motherboard form factors such as ITX, ATX, micro ATX, mini ITX, etc. The cases are designed to be compatible with only a few of these motherboard form factors so make sure your motherboard is on the compatibility list for the case.
  • Size: One of the main reasons to go for a horizontal PC case rather than a standard vertical design is the size of the case. Before you buy a horizontal PC case, you must ensure that the size of the horizontal case is suitable for your desk space. As you may already know, horizontal PC cases save a lot of space in terms of height, but they take significantly larger space in terms of length and width.
  • Cooler and GPU Compatibility: Other than the motherboard, you also need to check the compatibility of the case with the CPU cooler as well as the graphics card. It is even more important now as the new generation of graphics cards is quite large in size. As for the CPU cooler, you might already know that high-capacity air CPU coolers are quite large in size. And as the height of the horizontal PC case is already too short, their compatibility with large CPU coolers is even narrower.

While the features mentioned above are some of the most essential features of a PC case, you need to know a lot more before you finalize your choice. Fortunately, you won’t need to browse hundreds of options in the market as we have already shortlisted the best horizontal PC cases right here. We will also inform you a lot more about the essential qualities of a PC case up next in our Buying Guide for the best horizontal PC cases, so make sure you stick around for that.

Buying Guide For The Best Horizontal PC Case

Nowadays, custom PC builds are significantly more popular than a pre-built system. Building a customized PC allows you to choose the components that you want the most, along with the best-suited PC case for your taste. For that, there are a lot of brands in the market that specifically design PC cases in a variety of form factors.

Today, we have covered the best horizontal PC cases on our list and offered detailed information along with each of our picks. We have also offered a collection of the best features along with each of our picks to give you a comprehensive insight into what you will get when you buy the case. If you still want to know more about horizontal PC cases, make sure you check out our buying guide for the best horizontal PC cases.

1. Motherboard Compatibility

Irrespective of what type of PC case you are buying, you should always check the motherboard compatibility of your case to get the best results. If you have been planning to build a custom PC for quite some time now, you might have already selected the components that you wish to install in your system such as motherboard, CPU, GPU, RAM, etc. Thus, your case must be perfectly compatible with all of these components in order to create a fully functioning custom PC. In the compatibility section, we will recommend that you primarily check the motherboard section. Usually, it is mentioned at the earliest so that you can get a quick idea about the compatibility of your case. Simply check the type of your case and make sure that your motherboard is of the same form factor. Generally, there are a variety of options for motherboards such as ATX, micro ATX, mini ITX, and many others.

2. CPU Cooler and GPU Support

Apart from the motherboard, the 2 most important components of your PC that usually cause compatibility issues are the CPU coolers and GPUs. Before you finalize your horizontal PC case, you must ensure that it can house the CPU cooler of your choice. The air CPU coolers are quite large in size, depending upon the brand and quality of the air cooler you are buying. Even in the case of a liquid cooler or AIO, your case must be compatible with the same radiator size as the one included with your AIO.

Coming to the GPU, the major issue, in this case, is the GPU length. If the GPU cannot be installed in a case, you will have to get a completely different card which is not an ideal condition. And with the current market condition, you might not even get an alternative option for a long time. To avoid such problems, simply check the length of the GPU you want to install in your system and check its compatibility with the case. Case manufacturers usually mention supported GPU length in mm which should be higher than your GPUs length.

3. PSU Support

The PSU is also a major component of your system since you cannot turn on the system without a dedicated power supply unit. For the newer generation of CPUs and GPUs, the overall power requirement is quite high. Thus, you will need a fairly large PSU if you want to build a high-capacity gaming computer with the latest generation CPU and GPU. But for that, your case must be capable of housing such a unit without any problems.

For that, you can check the compatibility of the horizontal PC case against the PSU of your choice beforehand. Similar to that of a motherboard, the PC cases also have a compatibility standard for PSUs. PSUs are designed in standard form factors like ATX or SFX that must be supported by your PC case. While the majority of horizontal PC cases are compatible with ATX PSUs, a handful of options might only support SFX PSUs that are comparatively smaller in size.

4. PCIe Expansion Slots

Lastly, we will recommend that you thoroughly check the available PCIe slots on your case. You might be wondering whether you should check the PCIe slots on the motherboard or the case. Well, for the best results, you need to check the availability of PCIe slots on both ends. While the motherboard offers connectivity of PCIe-powered components, the case allows installation of the same via dedicated PCIe installation ports.

Apart from the graphics card, there are a lot of PCIe components that you might need in the future such as network cards, audio cards, additional USB hubs, tuner cards, etc. For that, your case must offer additional PCIe expansion slots. Even if your case is compact in size, you should prefer an option that offers at least 2 to 3 PCIe expansion slots in total to get a future-proof PC build.


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

PC cases are designed along with dedicated slots for cooling fans. Even if you are buying a horizontal PC case, you will still have the option to install the cooling fans of your choice. However, make sure that you install the fans in the correct orientation to get optimal airflow inside your case. Generally, the fans that are designed for standard PC cases can be installed into a horizontal case without any problem.

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

Well, most standard cases can be used in horizontal orientation without any problem. But, the only condition is that the PC components must be installed in such a way that the setup is similar to the form of a horizontal PC case. As there are no moving parts present in the majority of PC components, the orientation should not be a problem. With that being said, we will still recommend getting a decent horizontal PC case if you are going to place the case in horizontal orientation, just to be on the safe side.

Q. Do I need a PSU shroud inside the PC case?

The PSU shroud does not actually affect the performance of your system, or that of the PSU powering your PC. But, it definitely contributes to the aesthetics and helps to create a clean PC build, which is preferred by a lot of users. If your case comes with a PSU shroud, you can easily hide most of the large and ugly cables coming out of the PSU. It will make it easier for you to manage the cables inside your case while allowing you to customize your PC even further with dedicated lights or a figurine of your choice.
