The chassis that ensures all your hardware fits in confined space conveniently is SilverStone Technology GD09B. We consider it as the best runner-up horizontal PC case. A GPU like the Nvidia’s RTX 3080 can comfortably fit into the enclosure and boost the fps for mesmerizing graphics. You can also fit a Noctua NHC14s with ease with no height limitation, but any higher air-based cooler won’t fit.
The case will be an excellent replacement for your home theater system, but it cannot be used as a high-end gaming PC. The limitation is not having space for any liquid cooling radiator and enough clearance for a high-end CPU air-based cooler to fit in. The case comes with only one 120mm cooling fan, which is not enough for modern-day gaming PCs. If you are planning to overclock on this chassis, then you will be limited to small headspace. The chassis supports 7+1 expansion slots, which is more than enough for an ATX motherboard in a confined space. Being an HTPC case cable management is a bit tricky.

The orientation of this case is not limited to being a horizontal PC case. Tilt the case utilize the two-way vertical GPU mounting, and you are good to go. It’s all in one exquisite beauty built to mesmerize their owners and guests. The chassis is an open frame design installed with a 5mm tempered glass side window. We believe this is the best premium horizontal case.
This chassis has everything an expert modder can wish for, but it could give beginners a headache. The front instruction manual is difficult to grasp. We recommend YouTube tutorials for beginners. The front panel is missing a Type-C USB port, slowly gaining popularity and becoming essential shortly. If you still use optical drives, be sure that this horizontal PC case does not support their installation. The open-frame design cannot restrict noise level, and dust is an unavoidable consequence of using this design.

It is an excellent choice for professionals who want to create content with a high-end processing power for video editing or graphics work. The expansion cards have a substantial space of 345mm, allowing the installation of massive GPU sizes available in the market. The chassis comes with removable case filters on all openings of the computer case. Two External 3.5" hot-swap bays are an attractive option at this price.
The chassis is spacious with lots of room for experimentation, yet the cable management is difficult for a cleaned-up interior. The SSI-EEB compatibility is mentioned for this chassis; it has ample space to include an E-ATX motherboard, but it’s still tricky to fit an SSI-EEB motherboard. The reliability and long term operation design makes it a bit expensive. If you are a streamer, we would recommend you go for this chassis.
The brushed aluminum metal on the front is as rigid as a PC can get. It is suitable for data centers as well. A simple removal of case feet and installing a standard RA02 handle with four screws will let you install your PC into the rack. The positive pressure ensures that the chassis does not build up dust over time, and the equipment operates reliably as a server PC should. It can possess a 7+1 expansion card at the back and a two USB 3.0 Type-A connection on the front, which is essential to building a high-end PC.

This PC Case is also an addition to the list because of the vertical and horizontal orientation options. The chassis comes with an included base to allow vertical operation. We consider Antec VSK2000 as the best budget horizontal PC case. The chassis is compact and suitable for desk work. It’s a simple design with a tool-less ODD/HDD housing system for fast installation. The computer can provide a bare essential capability for productive work by supporting motherboards of Micro-ATX and Mini-ITX size.
The small desk footprint is an excellent deal, but some things require special attention to such close quarters inside a chassis. Antec decided to go for a TFX PSU. It’s a rare form of power supply that is hard to replace and costly if it gets damaged. Using a motherboard that supports OC RAMs won’t be a wise choice for this chassis. The clearance is pretty low using a Micro-ATX motherboard with high profile rams is not possible. Some users had to trim some parts of the case to adjust. It also doesn’t have a filter, which can lead to dust accumulation with time.
This PC case, surprisingly with an SFF, has a slot for an optical drive, which is a rare sight for this form factor. The build quality is clean, and the material used is rigid to give the overall package a solid feel. The sharp edges inside the case are mild and would not cause a cut or lead to bleeding. The horizontal PC case lid is easy to release with the press of a button. The support for USB 3.0 on the front is amongst the latest tech you can own. This chassis can easily be used as an HTPC in your living room. A low profile CPU cooler will easily fit under the roof.

SilverStone has their specific touch to aesthetics that they add to all their products. The brushed metal looks on the front door usually made from aluminum. SilverStone ML04 is another compact functional and horizontal PC case that this company has to offer. The size is suitable for small tabletops and office work. This PC Case is the best horizontal Micro-ATX Case. You can also use it as an HTPC with enough power to keep your home theatre up and running smoothly. The chassis can house a Micro-ATX motherboard and is small.
The CPU clearance is small and will require a low profile cooler such as the Noctua NH-L9i. This feature is an added cost as some processors come with preinstalled coolers and usually have higher profiles. The GPU clearance is also low due to the tight corners SilverStone had to make for component adjustment in SFF. Users have reported that the light indicator on the front is too bright for a room set up and sometimes nonadjustable. The chassis supports PS2(ATX) supplies, but the wires are a bit tricky to handle.
Not many chassis include a USB Type-C connection, which is the requirement for modern peripherals, but this chassis has Type-C and Type-A connection with HD audio jacks. The support for up to four 80mm fans in this form factor is above all others. The front door and power button are lockable to avoid an operation, which helps kids around the house. LED light is bright, but it is adjustable to the desired value. The chassis comes with a magnetic filter on top to avoid dust.

Fractal is known to give the most aesthetically pleasing computer PC cases. They are reasonably priced and well built. Fractal Design Node 202 is no exception to the fact, and it is the best horizontal Mini-ITX PC Case. The chassis supports PCIe 3.0 riser cards that can be made into a mid-range gaming PC with ease. Along with this, it offers enough airflow to draw away the heat produced by the components. The simple design can be placed vertically or horizontally. Horizontal placement makes a lot of sense.
There is no RGB on the chassis, and neither is any window to spot the inside hardware. You can save money by buying non-RGB components that are functional rather than aesthetic. Some people are not pleased with the logo being horizontal, but for this review, we think you wouldn’t mind placing your chassis horizontal as it’s meant to be that way. The filters are not easily accessible and require the dismantling of the chassis.
There are two USB 3.0 ports, and the dust filters have been strategically placed to avoid the accumulation of dust. The price is reasonable for any small gaming PC. The dual-chamber chassis allows heat transfer to be confined to specific chambers and keep the other components cool. It is helpful to have a high-end GPU or CPU that can cause heat transfer to each other during operation. The cable management is also relatively easy as fractal ensures premium cable management.
Chassis are essential to the aesthetics of your workplace, battle station, or gaming station. A horizontal PC case will not only make your tabletop look clean and minimalist, but the amount of power you can extract from some well-designed chassis is unparalleled.
If you are a mellow user and do not put your system under intense processing loads, then go for chassis compact and suitable for HTPC. Gamers should go for a relatively larger chassis with dual-chamber options for ease in cable management and efficient heat transfer. Filters are also critical to avoid dust accumulation. Some chassis offer positive pressure that allows improvement in dust accumulation.
If you live in a dusty environment, it’s better to have a chassis with easily accessible and replaceable filters. Connectivity is critical for peripherals to ensure that your chassis offers Type-C connectivity if you own equipment that uses this type of port. USB 3.0 can also improve your data transfer speeds, so a presence on the front panel provides easy and faster performance. Audio jack has equal importance HD audio jacks featured in some of our chassis to provide high-end sound. It’s utterly dependent on the requirement of the user. We hope you find the product you would like to pick for your smart PC installation.
