Building two separate PCs for your specific requirements can be a little expensive, and it also consumes a lot of space. However, this problem can easily be solved by using a dual-system case. A dual system PC case or chassis allows you to have two different systems in one computer case with separate processors, motherboards, memory, IO ports, and graphics cards. The only thing common would be the power supply and case fans. Not only a dual-system PC is cost-effective and saves space, but it is also easier to maintain and manage. The only slight disadvantage that I can think of is that you can be limited by motherboard options because, in a dual-system case, one system has to use a mini-ITX motherboard, which may pose a slight problem sometimes because of expansion or availability reasons.
While most of the users may prefer a single system for both gaming, streaming, and work but if you are a professional or an enthusiast who does not want to compromise on anything, then it is a wise choice to have two separate systems or even a dual system using a dual system computer case. Different users may have different requirements for the dual system as some want to build it for gaming and streaming while others may want to build it for gaming and work. You can also have different operating systems in a dual system case for your specific work needs, e.g., in one system, you can run Linux, and in other, you can install Windows. Also, in dual-system cases, you can have different CPU options as in one you can use Intel processor and in other, you can have AMD, to get the best of both worlds. So, if you are in search of a good dual-system case, then here, I am going to list down the best dual system PC cases so that you can have two different computers in a single PC case.
Top Dual System PC Cases
Below are the top dual system computer cases for setting a dual-system PC for gaming plus work.
[Solid Build, Dual System Kit Included, Affordable, Water Cooling Ready, Good Airflow]
Phanteks Enthoo Mini XL DS is probably the best dual system case you can get for building a dual system PC. It is an upgraded version of the Phanteks Enthoo Mini XL case with all the issues sorted out. It is a Super Micro Tower case, which is a unique form factor. The case can support Micro ATX and Mini ITX motherboard simultaneously, which means you can run two systems independently of each other. The case is quite enormous and has good airflow. It comes with plenty of fan mount points at all locations, and two 140mm fans at the front and one 120mm at the rear come included with the case. The fan speed can be controlled using the PWM Hub, included with the computer case. There are separate I/O ports and power switches for each system, and they include two USB 3.0 ports and Audio port.

Other Dual System PC Cases
Below are some other dual system cases that are worth checking out.
Power Supply Splitter
If you want to run dual systems using a single power supply, then you need a PSU Splitter. It is the best way for running dual system cases that support only a single power supply. One such PSU Splitter is the Phanteks Power Splitter that takes one 24-pin and two 8-pin inputs and divides it into two 24-pin output, two 8-pin and 4-pin output for two separate systems. The Power Splitter is compact and can be mounted easily inside the case either by using Velcro mount (Universally) or Drop-N-Lock system (only with supported Phanteks cases).
The Phanteks Power Splitter’s Patented Isolated Dual System Technology allows a dual system configuration to operate independently of one another. It means Powering ON/OFF on one system will not affect the other and vice versa. As long as one system is running, the power supply will be fully operational until both systems are off. The Anti – Noise Inrush Protection Circuit of this power splitter helps to protect and stabilize the voltage signal level and also enables the power supply’s various protection to prevent damage caused by inrush current surges.
The power splitter can provide 452W of maximum power for both systems, which does not include graphics card power consumption because graphics cards have to be connected directly to the PSU using the PSU’s 6-pin/8-pin PCI-E connector cables. The minimum PSU requirement is 600W and above (based on total power consumption). The extension power cables come included with the power splitter.
|Phanteks Power Splitter Specifications|
|Motherboard Support||ATX, EATX, mATX, Mini ITX|
|Input Connectors||24-pinx 1, 8-pin x2|
|Output Connectors||24-pin x 2, 8-pin x 2, 4-pin x 4|
|Output Max Wattage||452W (system 1 + system 2 combined, GPU power consumption excluded)|
|Minimum PSU||80+ Bronze 600W or above|
Dual System Power Supply
Revolt X PSU is a powerful dual system power supply from Phanteks. The PSU is available in two wattage capacities: 1000W and 1200W (Revolt X 1200 and Revolt X 1000). It is an 80 Plus Platinum Certified power supply that offers 92% efficiency at 50% system load. The power supply is made in collaboration with Seasonic, which is known for making high quality power supplies both for industrial and consumer use. The Revolt X PSU comes with a powerful single 12V Rail that carries a current of 83A and 100A for 1000W and 1200W models, respectively. For graphics cards, it offers eight 8-Pin (6+2) PCI-Express connectors.
It is a fully modular power supply with extra-long cables (up to 810mm) so that they can reach to every corner of a dual system case easily. The cables for the motherboard, graphics card, and CPU power are braided while other cables are not. For cooling, it uses a 135mm fan with fluid dynamic bearing. The PSU features a semi-passive operation where the fan remains off when the load is under 40% for completely quiet operation. This dual system power supply uses in-built power splitter, which means dual system configuration can operate independently of one another, and powering on/off on one system will not affect the other and vice versa. The build quality of the PSU is great, and it has all the protection features that include OPP, OVP, SCP, OCP, OTP, No-Load protection, and Reset Protection.

There is no denying the fact that dual systems are easier to manage, and they do save a lot of space. However, these cases cater only to specific users, as some do not need two systems, and some prefer to build two different systems using separate cases. In my opinion, a dual system setup using a single case is more convenient in the majority of the scenarios because of the various advantages they offer. If you have any queries then do ask them in the comment section below.
