Building a dual system has many uses with one of the most popular ones being that you can use one system for gaming and the other for encoding (Streaming and recording).
As cool as that may sound, there is no doubt that building two computers in one case will present you with multiple challenges to overcome. Things like cooling, space management, cable management, and more.
The least that you can do is get a very good dual-system PC case. Not sure which one to pick? In that case, check out our top 3 choices!
1: Phanteks Luxe 2
Best Elegant Case
This is one of the most powerful cases that Phanteks has ever build – if not the most powerful. It offers support not only for dual systems but also for dual PSUs.
Yes, it’s big. But, for a good reason. With great modularity, tons of storage, great cooling, plenty of space for everything, radiator support with 480mm of clearance, and support for SSI-EEB motherboards, this is an absolute monster that’s designed to support monster builds!
We assume that you’re looking for details, so let’s start with storage capacity first. As far as 3.5-inch drives are concerned, we’re looking at enough room for 12 bays. 8 of them can be placed on the side and 4 more on the bottom section.
Then there’s also enough room for 11 SSDs (Or 2.5-inch HDDs) with 3 slots being dedicated for SSDs only. That being said, do keep in mind that most of the storage room is being shared with both HDDs and SSDs.
As for cooling, you’ve got the option of mounting up to 15x 120mm fans, 5 spots for radiators with the front and the side offering up to 480mm of clearance, and plenty of vents everywhere so that the computers will be able to breathe.
Regarding space, the main section has enough clearance for CPU coolers up to 195mm, which is frankly more than enough for anything out in the market. But, the second section can’t fit anything more than 80mm.
Thankfully, there is more than enough room to fit dual or even triple radiator-setups. So, as long as you’re comfortable with liquid-cooling, that’s not going to be an issue.
For those who don’t want dual PSUs, consider getting the Phanteks Revolt X 1200 which is made for dual-systems.
- Plenty of space for components
- The dedicated PSU is a superb idea
- Modularity is absolutely amazing (Can freely swap out radiators, fans, drive slots, PSUs, GPUs, etc)
- Numerous vertical GPU mounts
- More PCI slots than you’ll ever need
- Enough clearance for radiators up to 480mm
- Offers the option of mounting multiple liquid coolers at once
- 5-year warranty
- Maybe not the best option for those who want something fancy
2: Corsair Obsidian 1000D
Best Dual System PC Case for Super Tower Enthusiasts
As a super tower, the Obsidian 1000D isn’t just extremely large, but also extremely heavy. 65 pounds or 29.5 kilograms, depending on your location. And that’s just the case without the dual system installed.
Does it offer enough room and features to justify that insane weight and size? Actually, yes. The only reason that we’re not branding this one as the best choice is because the case alone costs as much as a mid-range gaming build. Ouch.
Still, for those of you who can afford it, this is one of the best cases that have ever been made. With enough room to mount 2 PSUs, an E-ATX motherboard along with an ITX one, 4 radiators at the same time, and 11 drive slots, this is another monster that you should seriously consider for a dual-system build.
By the way, both the front and left side panels are tempered glass which adds a lot of beauty to the overall build. Especially for RGB lovers.
Speaking of design, the Obsidian 1000D offers something rather unique – double doors on the right-side panel and dual mounts for fans or radiators.
All of that effectively offers 18 fan mounts. If this isn’t enough to cool your build, then consider moving to Antartica cause we highly doubt that you’ll find anything better.
And speaking about cooling, this setup is possible thanks to the built-in fan controller. That being said, if you seriously intend on mounting 18 fans in there, then you’ll also need a few other adapters to make that work.
- Overall modularity (The removable radiator tray is brilliant)
- Plenty of space
- Lots of dedicated slots for 3.5 and 2.5 drives
- Vertical GPU mounts
- Can host multiple radiators at the same time
- Can fit dual radiators up to 480mm
- Tempered glass plays well with RGB components
- Makes cable management a child’s play
- Extremely big and heavy
- Very expensive
Overall, some of the best features that the Obsidian 1000D offers compared to other cases is the extreme ease of use, extra modularity, and lots of options on how to build a machine that’s not just powerful, but beautiful as well. However, the high price-tag can be an issue for lots of builders.
Phanteks Evolv X
Best Dual System PC Case in Terms of Simplicity
All the modularity advanced features that dual system cases offer is great and everything. But, some people can’t help but feel overwhelmed with them. If you belong to that category, consider the Phanteks Evolv X.
One thing that makes the Evolv X stand out compared to other dual system cases is that it offers a very simple design. PSU and 3.5-inch drives go to the bottom section, SSDs on the right-side panel, fan support on the front, top, and back, etc.
It’s more or less the same design that you’ll find in normal ATX cases. But, with that being said, those who want to take the leap and go all out are free to do so thanks to the optional modularity and accessories that the Evolv X offers.
We’re talking about enough room to add 9 SSDs, 10 HDDs, vertical GPU mounts, 420mm radiators on the front, 7 PCI slots, 7 fan slots, 190mm of CPU clearance, and 435mm of GPU clearance!
The best part is that it manages to offer support for a monster build without coming at a huge size or weight. It’s considerably smaller and lighter than any of our other options. To be more precise, think of a slightly larger, standard ATX case.
This is possible thanks to the Revolt X 1200 PSU which eliminates the need for installing a second PSU and thus, also the need for more room that’s otherwise needed to host a secondary power supply.
With all of that being said, as far as modularity and features are concerned, the Evolv X is obviously no match for monsters like the Obsidian 1000D. But, it’s not meant to be one either.
- Relatively small factor
- Tons of options for storage
- Good cooling
- Plenty of room for powerful components
- Vertical GPU mounts
- Tempered glass on both sides
- Good cable management
- Relatively cheap
- Can’t compete with our other options in terms of modularity and features
- No dual-PSU support
Things to Look Our for When Buying a Dual System PC Case
Dual system PC cases are special in quite a few ways. Bigger, more powerful, more feature-rich, more modularity, more mounting options, etc.
That’s why we need to keep en eye out for a few things when buying one. Here are some of the most important ones:
- Vertical GPU mounts: They are pretty much a necessity on a dual-system.
- Modularity: Extra modularity is needed with dual systems. For example, maybe you don’t need a second PSU. Can you use that extra space for drives? You get the point.
- Radiator support: In other cases, that’s just a nice option to have. But, on a dual system, it’s a necessity. After all, bulky coolers aren’t going to fit on the second system.
- Drive slots/bays: You’re running two computers on a single case. Make sure that it can satisfy the storage needs for both of them.
- Cooling: All that additional heat that is created with two systems needs to be dealt with. Look for cases that offer a ton of room for fans.
- Pre-installed fan hubs: All these fans need to be powered and controlled efficiently.
- Upgradability: It would be a shame to buy a monster case that can’t fit a good graphics card or cooler. That’s one of the reasons that good modularity is also a must.
- Cable management: Cable managing one build is tough as is. Imagine having to do it with two at once.
All of the cases that we selected fit those requirements and more. But, do keep them in mind for future purchases.
That’s all for now. If you went through all of our choices and got overwhelmed by everything that they offer, here’s what fits each kind of user in a nutshell:
- Phanteks Luxe 2: Offers dual-system capability while still keeping a relatively low-key profile
- Corsair Obsidian 1000D: A monster in size, weight, features, and modularity. One of the best cases to get, but also very expensive
- Phanteks Evolv X: Dual-system case on an ATX size without sacrificing too many features. Also very simple and straightforward to build in
