The chassis is open frame construction with a side window made of tempered glass measuring 5mm. This premium horizontal computer case is our favorite. The chassis offers everything an experienced modder could want but can cause problems for beginners. The front instruction manual can be difficult to understand.

It is missing a Type C USB port on the front panel. Type-C USB ports are slowly becoming more common and essential. If you are still using optical drives, make sure this horizontal computer case doesn’t support their installation. Open-frame designs cannot reduce noise levels and dust are an unavoidable consequence of this design.

With high-end components in this chassis, any new game is guaranteed to run smoothly. It can accommodate a 480mm radiator with a liquid reserve to boost your CPU’s speed. The GPU does not have any restriction to airflow and performs well under OC conditions.

  • Expensive Pricing

Silverstone offers a solution if you are looking for computer systems that are small and compact but can still do the job. SilverStone Technology is the chassis that fits all of your hardware into a compact space. It’s our choice for the best horizontal PC case.

Nvidia’s RTX 3080 GPU can fit comfortably in the enclosure. This will allow for breathtaking graphics and a higher frame rate. Noctua NHC14s will fit in the case without restriction. Any higher air-based cooler will not work. Although the case is a great replacement for your home theatre system it can’t be used as an advanced gaming computer. It does not have enough clearance to allow for a CPU air-based cooler or liquid cooling radiator.

This case only comes with one 120mm cooling fan. This is insufficient for modern gaming computers. The chassis will not allow for excessive overclocking. The chassis can accommodate 7+1 expansion slots. This allows for an ATX PC case motherboard to fit in a small space. The cable management of an HTPC case is a little tricky.

The filter is designed to keep dust out. SilverStone used positive pressure to remove dust or other contaminants from the chassis. It makes maintenance easier and prolongs the component’s life. The front panel includes a Type C USB port, which is crucial for any modern-day computer case. A USB 3.0 port is also available for peripheral connections. The GPU has its own vent to help dissipate heat effectively and perform under OC conditions.

You can place the simple design horizontally or vertically. The horizontal placement is very practical. There is no RGB on this chassis and there is no window for spotting the hardware inside. Non-RGB components can be purchased to save money and serve a functional purpose.

Some people do not like the logo being horizontal. But for this review, we believe you would prefer to have your chassis placed horizontally as it is intended. The filters are difficult to access and will need to be taken apart from the chassis.

There are two USB 3.0 ports. The dust filters were strategically placed to minimize dust accumulation. This price is affordable for a small PC gaming case. The dual-chamber chassis keeps heat transfer in check and cools other components. It is important to have a CPU or GPU that can cause heat transfer between each other.

It has a simple design and a tool-less ODD/HDD housing for quick installation. It supports motherboards with Micro-ATX and Mini ATX case sizes. This computer will provide the minimum necessary capability to perform productive work.

While the compact desk footprint is great, certain items need to be carefully inspected inside a chassis. Antec went for a TFX PSU. It is a rare power supply and expensive to replace if it becomes damaged. It is not a smart choice to use a motherboard with OC RAMs.

Clearance is very low when using a Micro ATX motherboard with high-profile RAMs. Users had to trim parts of the case in order to adjust. There is no filter on the case, which can lead to dust accumulation over time.

The PC case is equipped with an SFF and has a slot to hold an optical drive. This is an unusual feature for this type of form factor. The build quality is excellent and the material used gives the package a solid feel. The edges of the case are gentle and won’t cause any cuts or bleeding.

7. SilverStone RVZ03

SilverStone RVZ03

1. 15.04 x 4.13 x 13.79 inches
2. Weight ‎10 pounds
3. Fan Count 2
  • 140mm ATX Power Supply
  • PSU Clearance 150mm
  • Cooling Fans Lacks PWM Control
  • Expensive Pricing

SilverStone RVZ03 has many colors and RGB flavors, but all variations share one thing: they are primarily vertical slim computer cases. It’s possible to use the RVZ03 horizontally. The only problem is that the CPU fan will not be visible. This can result in lower thermals.

The RVZ03 delivers excellent thermal results. Because of its three 120mm fan mounts, it’s one of the coolest Mini ITX case. This case can hold a dual-slot GPU up to 330mm long, a CPU cooler up to 83mm high, and an SFX power supply. You can also build an RTX3080 or R9 5900X rig within this case. You can keep your CPU at its stock clocks while you get a low profile, high-performance air cooling unit like the be silent! Shadow Rock LP, or the Noctua NH-12S.

You can store four 2.5 inch drives with storage drive support. But, it is important to note that a PSU greater than 140mm may make it impossible for one 2.5 inch drive mount to be used. This case can be used with AIO coolers. AIO coolers will not fit due to the limited clearance. You will likely need an air cooler to cool your CPU if this is what you are looking for. The RVZ03 is an excellent vertical as well as a horizontal computer case. It also looks great when used horizontally. The case should not be too hot, so you can monitor the CPU thermals.

Factors to Keep in Mind While Shopping Best Horizontal PC Case


Make sure your case is compatible with the form factor of your motherboard before you consider a horizontal computer case for your PC. Similar to a vertical case, the dimensions of your case need to match the dimensions of your motherboard. Also, you must ensure that your case has enough room for the components you will be attaching to your motherboard during the build.

Best Horizontal PC Cases

Form Factor

Make sure your case is compatible with the form factor of your motherboard before you consider a horizontal case for your PC. Similar to a vertical case, the dimensions of your case need to match the dimensions of your motherboard. Also, you must ensure that your case has enough room for the components you will be attaching to your motherboard during the build.


A horizontal case is better than a standard vertical one because of its size. It is important to ensure that the size and dimensions of your horizontal PC cases are appropriate for your workspace before you decide to buy one. Horizontal PC cases are a great way to save space, but they also take up a lot more space in terms of length and width.


Like the form factor, it is important to make sure that the horizontal case you choose has sufficient clearance for your CPU, GPU, and PSU. These specifications, as well as the dimensions of the chassis, can be found on manufacturers’ websites. You want to make sure there is enough space to fit everything, but enough to allow for proper airflow. This will not limit future upgrade options.

Front Panel

Front panel features are regularly updated with new USB ports and headphone jacks. Power buttons are also added. This is something you should check before you buy a horizontal case for your PC. The specifications and information about the front panel can be found on most manufacturer’s websites.

Frequently Asked Questions (FAQs)

Q1. Are case fans compatible with horizontal PC case?

Many cases have dedicated slots for cooling fans. Even if your PC is horizontal, you still have the option of installing the cooling fans that you prefer. For optimal airflow in your case, ensure that the fans are correctly oriented. The fans that are made for standard PC cases can usually be fitted into a horizontal computer case.

Q2. If space is not a concern, should I opt for a horizontal PC case?

The benefits of horizontal cases go beyond small footprints. It all depends on the build you plan and what your needs are. Horizontal cases are not recommended if you intend to build a gaming rig that is high-end and features all the bells, whistles, and other sports-related goodies. Although you can do many cool things with a vertical case, it is difficult to match the space-saving, display-worthy vertical towers that are available on the market. You should do what is right for you, your build & your budget.

Q3. Will a standard PC work with a horizontal orientation?

Standard PC cases can be used horizontally without any problems. Only one requirement is that all components be placed in a horizontal configuration. There are no moving parts on any of the important PC parts so orientation shouldn’t be a problem. If you want to place the computer case horizontally, it is a good idea to get a quality case.

Q4. Does the PC case need a power supply shroud?

PSU shrouds do not affect the performance of your system or the PSU powering it. However, the PSU shroud does make your computer look cleaner and more attractive. Many users like this feature. A PSU shroud can conceal most of the cables from the PSU. You will be able to organize your cables and customize your PC with dedicated lights or figurines.

Q5. Can horizontal cases be vertically oriented?

It depends on what case you choose and which manufacturer it comes from. Some cases can be used vertically and horizontally. However, if the case is advertised as a horizontal PC case I recommend it to be oriented horizontally. But don’t take my word on it. Look at the manufacturer’s website and read other reviews about your case. Then make a decision. It is possible to damage your components and lose your chance of returning your horizontal case if you buy a case that has been set up horizontally. A vertical tower is better if you need a horizontal PC case, but plan to use it vertically.
